Why do my dishes taste like soap after dishwasher? Anything could be wrong if your dishwasher recently started giving soap-tasting dishes after cleaning. You would also notice slight opaqueness on glassware, which is nasty.
Your dishes taste like soap after dishwasher due to excessive use of or low-quality detergent. Limescale buildup through water hardness, dirty water line/drain, and even clogged filter can cause the soapy flavor. Also, using pods against the manufacturer’s recommended liquid/powder detergent is a culprit.
Without fixing it, your dishwasher will keep putting soap on the dishes. A dishwasher not getting the soap off after rinsing is a common reason. But there are other culprits to be suspicious of. In extreme cases, replacing an old dishwasher saves more money thar repairs.
Why do my dishes taste like soap after dishwasher?
This section of the publication explains the various reasons your dishes taste soapy. And, of course, we also recommend various fixes to get your dishwasher back performing optimally.
Your dishes will taste like soap if you add excessive detergent to the dispenser. The dishwasher will rinse well when the soap is too much.
Most dishwashers arrive with a measuring cup for filling the dispenser with the correct amount of dishwasher detergent, use that.

You want a suitable amount of detergent for a normal full load of dishes in your machine. This is mostly the case with liquid or powdered soap. You may not have a measurement problem if using dishwasher pods.
Your dishwasher is susceptible to hard water problems. When the water in your area is too hard, it is challenging for the dishwasher to properly wash your dishes and get rid of soaps.
Dishwasher soap combined with hard water will produce a curdy precipitate known as soap scum.
Typically, hard water uses dissolved minerals, including magnesium ions and calcium ions, in high concentrations in the form of dissolved salts. Dishwasher soaps may contain sodium salt from stearic acid.
Nonetheless, soft water is quite alkaline and could as well taste soapy.
The first go-to solution is to clean or install the filter to adjust water chemistry if your dishwasher does not already have a filter.

You could also use a dishwasher descaler a few times a year to get rid of limescale buildup and hard water deposits.
Just run the longest, hot water wash cycle on your emptied dishwasher without adding detergent for 30 minutes. While the wash cycle is active, add a box of descaler to the bottom of the dishwasher.
Run a different wash cycle after the hot water cycle is complete.
A dirty or clogged filter will cause your dishwasher to produce dishes that taste like soap. The dishwasher soap you use accumulates in the filter after a long time of several dishwashes without cleaning it.
The solution is to remove the dishwasher filter from the bottom of the tub. You may have to remove a few screws to remove it from its housing.
According to Bosch, you should use a toothbrush to get rid of visible debris on the top of the filter and give the housing a thorough brushing.
Simply dip the brush in a mild powder or liquid dishwasher detergent to eliminate mineral deposits and tough food clumps. Finally, rinse off the soapy residue from the filter. Wipe the filter housing dry.
Depending on your dishwasher model, you may have multiple water filters in the interior. Refer to the product manual or search your dishwasher model number online for steps to clean the filter.
You may have to replace the filters if damaged. Note that some dishwashers come with permanently installed filters, you only have to clean them.
Speaking of distilling, can that your coffee maker distill water?
Dishwasher soap quality
The quality of dishwasher soap you use can be the reason your dishes are coming out so soapy.
We used a super cheap generic brand soap in one of our reviewed dishwashers, but the result was not pleasing. We also noticed that the dishes came out feeling and tasting like soap.
The glassware looked cloudy and, of course, slippery to touch. Heated dry and air dry will merely dry the soaps on the dishes.
The solution is to switch to high-quality soap as we did. The difference will be immediate, so you no longer have to hand-rinse your dishes after dishwasher wash/rinse. In our Bosch dishwasher test, we switched to these detergents for these best results.
Below are the high-quality soaps we used to eliminate the soapy flavor:
- Finish All In 1, Dishwasher Detergent – Powerball – Dishwashing Tablets – Dish Tabs, Fresh Scent, 94 Count Each
Why we used Finish
This Finish detergent was able to soften the tough dried-on oatmeal and baked-on lasagna. The stubborn disappeared within seconds, leaving no soapy flavor as well.
No doubt, the cleaners are powerful for all stubborn stains on your dishes.
Normally, you want to pre-soak. Finish uses a unique Powerball that removes grease and helps the machine scrub off dried-on and burnt food.
- Cascade Complete Dishwasher-Pods, ActionPacs Detergent Tabs, Fresh Scent, (Packaging May Vary), 78 Count
Why we used Cascade
Detergents with complete ActionPacs use 25% more cleaning power, and so does this Cascade detergent. This detergent is also phosphate-free.
If the dishwasher soap you use does not dissolve quickly, the dishes will come out soapy. Cascade dissolved so fast during our test, releasing the needed grease-fighting power for proper wash and rinse.
Cascade could clean a 24-hour stuck-on mess on our low-water consumption dishwasher quicker than we expected. Of course, we did not have to pre-wash, we only scraped off food remains.
All in all, it is necessary to invest in a good dishwasher liquid or powder. Remember not to overfill the reservoir, you could even fill it halfway.
Some dishwasher manufacturers do not recommend using pods. Pods are typically solid and may take longer to dissolve, preventing the dishwasher from eliminating the soapy taste. Even the best Comfee dishwashers are against pods.
Pods can also result in detergent buildup in the dishwashing machine.
If you have been using pods, consider switching to liquid or powdered dishwasher detergent.
If the water temperature is not hot enough, the dishwasher will not be able to wash off the soap.
In most cases, your dishwasher needs to heat up to 120ºF to 160ºF for the dishwasher detergent or pods to dissolve.
The simple fix for this problem is to make sure the water temperature is up to the suggested temperatures in your dishwasher.
Otherwise, the internal dishwasher thermostats could be faulty. Use an external thermostat to check the water temperature, or have a repairman do the job.
The heating element could be faulty if the water temperature is lower than usual, which requires a replacement. Report the problem to your dishwasher manufacturer for a fix.
Dirty water line
A clogged water line or drain will cause the soap taste you are experiencing on your dishes.
This is because your dishwasher cannot empty existing soapy water and replace it with fresh water. The dishwasher will keep passing the soap on the dishes, resulting in the soapy flavor.
To fix this problem, inspect the tightness of the water line and drain. If loose, try coupling it with pliers to seal the rubber gasket.
Avoid tightening the seal too tightly to prevent stripping the threads, or causing a leak.
You could try installing a replacement water inlet valve. Secure it firmly in place and reconnect the wires and hoses. You could also replace the lower kickplate panel before restoring power to the machine.
