What Dishwasher Water Softener should you use?

Water softeners remove the calcium, magnesium ions, and other minerals that are found in hard water. When these are removed, you will get what you call a “soft water” that is very compatible with soap and extends the life of plumbing. If you aren’t sure of why you should get a water softener for your dishwasher, you will know soon enough in this article.

Dishwashers need soft water to wash and rinse dishware; otherwise water stains will be left behind on the dishes and interior racks and walls of the dishwasher. There is a certain measurement on how “hard” water is, which is measured in terms of grains per gallon (GPG) or milligrams per liter (mg/L).

If you had your water tested take note that soft water measures only 1 GPG (17.1 mg/L) or less while hard water is around 7-10.5 GPG (120 – 180 mg/L).


What are the effects of hard water to your dishwasher?

The use of hard water has many other cons apart from the abovementioned water stains. These are:

  1. Hard water causes soap scum stuck and dried in the interior or the filter of the dishwasher.
  2. Hard water causes limescale buildup in the interior. Not only that, the plumbing connected to the dishwasher is also affected by this buildup. This is because the minerals found in the hard water precipitate inside pipes, which greatly reduces flow and eventually lead to clogging.
  3. Hard water reduces the ability of soap to lather, which results to the inability of the dishwasher to thoroughly clean your dishes.

There are many ways to soften the water used for your dishwasher. You can filter your house water by distillation or reverse osmosis or adding packaged chemical softeners, or running it through a machine that softens water. The methods you can use vary from dishwasher to dishwasher.


What is the best way to soften water for your dishwasher?

As previously mentioned, there are several methods you can try to soften the water used by your dishwasher. However, not all can be effective for your dishwasher. The first thing that you must do is measure the hardness of the water to know the appropriate action to take.

You may get this information from your local town hall water department if you use public water supply or your private well. If they can’t confirm the level of water hardness from your well, you may take a water sample to a local water-testing lab to test your water hardness.

If this can’t be done, there are commercially sold water hardness test kit that you can purchase such as the:


HM Digital TDS-EZ Water Quality TDS Tester

HM Digital TDS-EZ Water Quality TDS Tester, 0-9990 ppm Measurement Range, 1 ppm Resolution, 3% Readout Accuracy
  • Economy model that is ideal for end-users. Highly efficient and accurate due to its advanced microprocessor technology.
  • Hold Function: saves measurements for convenient reading and recording and battery life is approx. 1000 hours of usage and power source is 2 x 1.5V button cell batteries (included) (LR44 or equivalent)
  • Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Display: large and easy-to-read LCD screen.


You may also not need to do anything of the above and just spend some time observing how your dishwasher performs. If you see that it’s not cleaning thoroughly, it leaves water stains on your dishware, and leave annoying soapsuds all over the machine, then you’ll immediately know that your water is hard.

Some water softening methods that you can use are the following:

  • Boiling the water – Although this isn’t really recommended for dishwashers due to the amount of water needed to be boiled and the fact that it wastes too much gas, you can use this instead for bathing, brushing teeth, etc.
  • Adding ammonia, lye, baking soda, or borax – This works great if you intend to add soap along with it so it is recommended for doing the laundry. This method won’t soften the water, but instead hinder soapsuds from forming.
  • Installing a mechanical water softener – This is the most efficient way especially if you want the entire water supply in your home to be soft. The downside is the cost of operation.
  • Using a specialized water softener – There are water softeners in the form of salts that can be really effective for dishwashers.

Key Takeaway: Remember to use the best method or option for you. If you intend to use a water softener only for the dishwasher, consider using salts to pour into the machine. If you want to have soft water all over the house, consider installing a mechanical water softener.


How to use salt as water softener for dishwasher?

Follow the step-by-step guide below on using salt to soften the water used by your dishwasher.

Step 1: Purchase the right water softener salt formulated for your dishwasher. Not all types of dishwasher use salts so ensure you have this tiny container built into your dishwasher where the salt will be lodged. An example is the:


Finish Dishwasher Water Softener Salt For Bosch Dishwasher 2-Pack 8.8 Lbs

  • #1 Recommended by leading Dishwasher Manufacturer
  • Reduces hard water residue in the dishwasher. This results in a cleaner dishwasher and dishware
  • Only to be used in dishwashers that have a water softener container


Step 2: Find the location where you will lodge the salts by removing the lower rack of your dishwasher. The location of this container may vary so check your manual to exactly pinpoint it. Remove the lid that covers the salt container by unscrewing it.

Step 3: If adding salt for the first time, make sure to fill the salt container with water first. You don’t need to do this during subsequent refills. Afterwards, slowly fill the container with salt. Most containers hold approximately 4½ cups (1.0 kg) of salt. Check out the:


Miele : Somat Dishwasher Salt (B1640) 1.2kg

Miele : Somat Dishwasher Salt (B1640) 1.2kg/Packaging may vary
  • SOMAT - The special Salt ensures soft water and lime protection while dishwashing. Tap water contains lime, which can be deposited on dishes and in the dishwasher
  • ULTRA PURE SALT QUALITY - Somat coarse-grained dishwasher salt is completely pure and free of insoluble ingredients, just what your dishwasher needs! Packaging may vary
  • HIGHLY EFFECTIVE: Cuts right through hard water residue and limescale deposits in your dishwasher, eliminating existing buildup. A cleaner wash, every time!


Step 4: Clear out the excess salt found on the rims of the salt container. You can spoon the salt out if you have put in too much. Replace the salt container lid and tightly screw it. You’ll know when you’ll have to refill the salt, as the sensor will update it on the control screen (if you have it).

Key Takeaway: The use of salt for softening the water used by dishwashers is a relatively cheaper option. It is also centralized to the dishwasher so you’re sure that it only uses soft water without you spending too much on other water softeners.



There are a lot of options to use for your dishwasher water softener. You can opt for the expensive but hassle-free mechanical water softener or settle for a cheaper water softener salt that must be refilled from time to time. Whichever you choose, it’s great as you’re maximizing the cleaning potential of your dishwasher.

How to fix and replace your Dishwasher Overflow Valve?

The overflow valve is found in the air gap mounted on your sink next to the faucet. When the dishwasher overflow valve is filled with water that it spurts out of the air gap on your sink, you know that something is wrong with the tubes connecting your dishwasher to the correct outlets.

The problem only occurs when you run the dishwasher as the dirty water used to clean the dishes need to go somewhere. You will need to check the air gap and the two hoses connected to its bottom. You can try the method below to troubleshoot your dishwasher overflow valve.


What is the step-by-step procedure on fixing and replacing dishwasher overflow valve?

You will find below the steps on how to fix your dishwasher overflow valve, which is essentially part of the air gap device. If you need to know more about replacing the dishwasher overflow valve, there is an article found on this website about installation of an air gap that best suits that topic. Onto the guide:

Step 1: Turn the water supply valves off before you start doing anything. Removing the hoses may result to the continuous flowing of water. You may also want to turn the electricity to the kitchen circuit breaker off.

Step 2: Remove the air gap or the protruding device installed to your sink or countertop next to the sink. You may uninstall it by using adjustable pliers to loosen the slip joint found underneath the sink from where it is installed.

Step 3: Remove the two hoses connected to the air gap. These are the hose connected to the dishwasher and the hose connected to the garbage disposal. What connects the hoses to the main body of the air gap can either be a slip joint or a hose clamp. Remove them by using pliers. If you need to replace clamps, try:

  • Corrugated Plastic hose
  • 72 inch hose
  • Attaches to discharge outlets with 5/8-Inch, 3/4-Inch and 1-Inch connections.


Step 4: Trace the connections of both the hoses and remove them from their sources, which is the dishwasher and the garbage disposal. You may want to check the connections carefully to see if there are any obstructions or clogs.

Step 5: Take the hoses and fittings outside and use a garden hose with strong pressure to wash down the hoses. Use the pressure to wash down any debris, dirt, or obstructions found in the hoses. Also check underneath the sink if there are big items blocking the path of the hoses. Arrange these items accordingly.

Step 6: After all the hoses and fittings are thoroughly cleaned and washed down, reattach the hoses to the proper sources and secure them with slip joints of hose clamps. Return the air gap complete with the cleaned dishwasher overflow valve into the sink where you previously took it. Again, secure it tightly using pliers.

Step 7: Turn on the water supply lines and circuit breaker that you turned off prior to the start of the DIY project. Connect the dishwasher to power after you’re sure that everything is secured in the right places and turn it on. Test if water still comes up to the dishwasher overflow valve.

Step 8: If things are back to the way they were and you found no leaks or clogs, then congratulations on a job well done. Otherwise, you may need the help of a plumber to determine what’s wrong with the line or buy new sets of air gap kit and hoses. Getting a device to control water flow might also help, like the:

If you have managed to install the air gap yourself, you will know exactly how to disassemble it and find out the root causes by checking the valves, the connections, and the hoses. This step-by-step guide is aimed at troubleshooting and fixing the problem, rather than replacing any part mentioned in the guide.

What causes problems in the dishwasher overflow valve?

When you encounter problems or overflowing in the dishwasher overflow valve, most likely, the problem lies in the air gap, disposal hose port, or the hose connected to the air gap. Either any of these parts are clogged or it is obstructed by something big and heavy.

However, there are other problems that may cause problems in the dishwasher overflow valve such as:

  1. Food particles are stuck in the hose. Instead of going straight to the bin, food particles may get dislodged into the house because of build up of grim and grease that attracts food to stick.
  2. You forgot to remove the plug in the garbage disposal (this is very little minimal error. Ensure to check this before disassembling anything).
  3. The garbage disposal bin is full or there is something obstructing it. Once this happens, no water may go to the bin, which causes the waste to go up to the dishwasher overflow valve.


Key Takeaway: It is important to immediately fix any problems in the air gap and dishwasher overflow valve because it may cause dirty water coming from the dishwasher to be pushed back into the appliance (also called backflow) and contaminate any dishes or utensils inside. Dirty water should be heading straight to the disposal. Remember, wastewater draining back into the dishwasher is a health hazard.



Repairing your dishwasher as soon as it encounters any problems, whether clogs or leaks should be addressed right away. It really doesn’t matter if you are a seasoned handyman or have very little to no idea about fixing things, as long as you understand and know how to follow directions. Problems such as those that involve parts like the dishwasher overflow valve is not that difficult to troubleshoot and fix.
