How To Fix Bosch Dishwasher Not Dissolving Tablet

My Bosch dishwasher had just started not dissolving tablets and I was in need of some help to fix it? I cleaned the filter and checked to see if the door was shut properly, but none of these options helped me resolve this issue.

I got my problem checked thoroughly by an expert and he got the problem fixed. The steps that I tried during the entire operation are mentioned below in the article.

Check The Drain

The first thing you should check is your drain. The machine can’t do its job if it doesn’t have room to put dirty water.

If you see a build-up of white, flaky substance in your disposal or drain, it might be that you are using too many dishwashing detergents, and they are not dissolving properly in your water.

To ensure things run smoothly every time, try switching brands or running hot water while draining out dishes after a wash cycle has been completed.

A common misconception is that hot water breaks down fats and oils, when in fact only cold water can dissolve fats.

Clean Up The Filter

If you have a problem with your tablet not dissolving, and ending up in gross, hard-to-clean spots in your dishwasher.

Try cleaning out your dishwasher’s filter. Once or twice a year you should give it a thorough cleaning.

Here’s how: Fill up your sink with hot water and detergent (you can use regular dish soap), then slide out your dishwasher’s filter—it looks like a tray that sits at floor level on one of its racks.

The water will dissolve any food particles stuck to it (and anything else). Once clean, rinse thoroughly before putting back into place. You might be surprised by how much stuff comes off!

Disassemble The Machine

First, you’ll need to get down and dirty and disassemble your dishwasher. Open up your machine and look for a large plastic tub (it’s often white or yellow) on either side of your washing chamber.

These contain all of your tablets, including any that are stuck in place. Remove them with a pair of tongs or a sponge.

Unscrew these pieces from your machine if necessary to reach each tablet that’s clogged within them. Afterward, clean out any extra grime from inside to avoid future problems.

Residue In Water Inlet Valve

Some dishwashers have a rubber water inlet valve that may be clogged. The device washer can still turn on and start. But it will stop working after a few minutes or when it begins to wash dishes.

If you see residue or suds inside of your dishwasher, you’ll need to open up your dishwasher to remove any buildup inside of your water inlet valve.

With an adjustable wrench, twist off any fittings or knobs attached to your water inlet valve until you find its screw connector beneath them. Try to use a Phillips head screwdriver to loosen and unscrew your drain pipe’s connecting collar


Remove Bad Mice And Other Pets

If your dishwasher has stopped dispensing soap, it could be because a small mouse or other pest has decided to take up residence inside.

If you can, try and get rid of any animals that have made a home for themselves inside your dishwasher.

Otherwise, you’ll end up spending an inordinate amount of time removing vermin from within the machine before repairing it.

The first close off all drains leading into the machine (but make sure no water is flowing into or out of them) and leave them alone for a few days.

During that time, they should either venture off in search of food elsewhere or drown within their newfound house.

Clean With Vinegar

Vinegar has a number of household uses, and it’s especially handy when cleaning your dishwasher.

When you run your machine without any soap (make sure to use rinse aid, though), run a cup of white vinegar through first to clean out anything stuck in there.

White vinegar is so effective because it dissolves soap scum and hard water deposits. In fact, you can use it to wipe down all of your kitchen appliances and countertops as well.

It leaves everything with a nice shine and a subtle apple scent!

Vinegar also works as an effective odor remover. Plus it has antibacterial properties that make it great for cleaning fruits and vegetables.


Use pliers to gently remove all plastic components from your tap. Be sure not to break any of these; they’re quite delicate.

Take a screwdriver and tighten each bolt. Make sure you don’t overtighten or you may strip it, which could make the repair more difficult.

Once all bolts are tightened, reassemble components in reverse order and test functionality by running water through your tap for several minutes.

If water flows freely, you can be confident that your dishwasher is working properly again!

You may have to repeat these steps periodically if tablets continue to dissolve improperly. Your Bosch appliance should provide an accurate parts list and assembly instructions if you need them.

Your water must be hot for an effective wash. To test, run a normal cycle with no dishes or silverware and check that there are a minimum of 160F -180F degrees of water present.

Test both upper and lower spray arms if you want to solve the problem of the Bosch Dishwasher Not Dissolving Tablet.

The upper arm should reach 160F -180F within 3 minutes and show at least 180 degrees at 5 minutes.

You will also want to see hot water coming out of the bottom spray arm during every cycle; it is located on the left side when looking from outside and discharges underneath the left door flap.

If there is not enough heat you may have a clogged spray arm, which can be corrected by cleaning each sprayer individually.
