Question about Bosch 24 in. SHU5305UC Built-in Dishwasher
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.
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.
