Bosch dishwasher model shu3300

It sounds like the pump is pulsating trying to move water either in or out. It is stuck in one of the cycles with no water in the machine and it just hums.

    Same problem. Machines seems to run as normal, except no water is being circulated. I checked my water lines to see if they might be clogged. Water is sitting in the bottom of the machine trap.

Your machine has detected a "flood" condition and has defaulted to its flood mode. Meaning that only the drain pump will work until the flood is fixed.

Bosch D/W's are pretty slick, the entire unit is sitting inside a drain pan that's designed to catch an overflow (flood) keeping the water off of your floor. This overflow pan has a Styrofoam float that rises with the flood and trips the "flood mode". The water in the pan has to be removed allowing the float to drop back down before you can use your dishwasher again.

There are 2 ways to do this... the easy way and the hard way.

1.) Easy way---> Wait a few days. The water will eventually evaporate out of the drain pan all by itself. Takes longer than the hard way, but no tools are involved.

2.) Hard way---> (not actually "hard") TURN POWER OFF TO THE DISHWASHER! Remove the lower kick panels (below the door). Remove the 2 screws holding the water valve in place, and push the valve up as far as you can. Now use a "Shop-Vac" with a long crevice tool attachment. Stick the crevice tool in where the valve was... make sure to reach in there about 8 or 9 inches, (the safety float is in there on the left, you can see it with a flashlight) otherwise it won't reach the water. Now simply suck up as much water as you can. You won't be able to get it all, you just need enough removed to drop the float.

Now try your D/W... after a normal 2 minute drain, it should fire right up.

Bosch SHU3300 dishwasher stuck on hot water intake (w/ no power)

It sounds like the fill vlave is stuck open. This can happen if your pressure is low or if the machine is old. I would start by replacing the vlave.

Dishwasher doesnot drain

Once you ensure that the drain lines are clear, this usually means that the drain pump is stuck, clogged or faulty.

Try first unplugging power cord for ten minutes.

If this does not help, the pump is clogged or defective.

Use the number listed on the owner manual if you want to call a technician.

Enter model number on this website to find schematics and replacement parts.
