Bosch Dishwasher Humming But Not Working-An Ultimate Guide

If your Bosch dishwasher sounds like it’s working but it’s not, you’re not alone.

This can be confusing, as the sounds that come from this dishwasher are normally quite loud and pronounced.

This problem also happened to me when I used it for quite some time.

But if you know what you’re listening for, it will be easy to figure out what the problem actually is and how to fix it so that your Bosch dishwasher works properly again!

This article will discuss everything you need to know about your Bosch dishwasher humming but not working.

Check the drain hose

It’s a simple fix, but one that can easily be overlooked. If you own a Bosch dishwasher, check to make sure there is not a clog in your drain hose.

A clog can stop water from draining properly and create noise in addition to preventing dishes from getting clean.

 

To get rid of any blockage, simply pick up a plumber’s snake tool or run a coat hanger through your pipe.

Test the voltage

Before you attempt to figure out what’s wrong with your dishwasher, make sure it’s actually receiving power. Turn off all circuit breakers at your home’s breaker box and then flip them back on.

If your dishwasher turns on while you’re testing, shut it off again and then check each electrical outlet in your kitchen

(as well as other rooms in your house) to ensure that you don’t have a tripped GFCI (ground fault circuit interrupter) or loose wiring.

Test any fuses or breakers by replacing them one at a time; if that doesn’t solve the problem, try replacing an outlet with a new one,

but be sure to turn off electricity at the main box before swapping them out.

 

Replace heating element

If you still hear a buzzing, humming sound after running your dishwasher through a full cycle, it’s likely that your dishwasher’s heating element is either faulty or has failed.

To fix a faulty heating element, turn off power to your dishwasher at its main power supply and then unplug it.

Next, remove any screws or clips that might be holding on its casing and set them aside so they don’t get lost. Now unscrew and disconnect any connecting wires.

Once you have taken apart enough of your dishwasher to expose its heating element, check to see if it looks discolored or burnt.

Replace pump motor

Sometimes there can be a simple solution to your problem. Your dishwasher may just need to have its motor replaced.

The motor is responsible for pumping water in and out of your dishwasher so that it can work properly.

When it breaks, your machine becomes noisy, which you’ve experienced firsthand with yours. Simply replace it and you should be good to go again—no trips to repair shops required!

Replace the electronic control board

This device, located underneath your control panel, is responsible for receiving and interpreting commands from your control panel.

If it fails to interpret a command or properly send on command to another part of your dishwasher, then you’ll have problems.

Although it can be difficult to diagnose problems with electronic control boards, you can rule out certain components by unplugging them one by one.

Before taking apart anything electronic, check and see if there are any warning labels that tell you not to open up specific areas of your dishwasher; follow these instructions exactly as they are given.

Replace the electronic control panel

The majority of dishwashers feature a control panel that’s easy to remove and replace.

And, because it controls most functions in your dishwasher, replacing it can often get things humming again—at least for a while.

Your local hardware store or appliance center should have control panels for common brands like Bosch and Maytag.

If you do find a part that matches your dishwasher’s model number, it’s as simple as swapping out screws to put it back together.
