Bosh dishwasher modle shu330cu not draining or lighting up

That is the drain pump that is running, and it indicates that there is water in the base of the unit. You will need to unplug the dishwasher and pull it out. You can tip it forward to drain the water out of the bottom through the holes in front. Have some towels ready to catch the water. Now if you plug the dishwasher back in, the pump should not run But now comes the hard part - figuring out where the leak is coming from and fixing it. It could be from a hose, the drain pump, or the main pump. Bosch dishwashers are notoriously hard to work on, so I recommend calling in a professional DW repairman.

see the following causes:
Make sure you get water to the dishwasher. Check to see if the water shut-off valve (located under the sink) is open. If you get water to the dishwasher, but there is still no water inside during the fill cycle, the problem might be with a faulty water valve (located at the bottom of the dishwasher) see diagram
2) faulty float switch, test for open or faulty.
see the diagram attached.
God bless you

Hi


Thanks for using FixYa. To start with check the water inlet valve which is located behind the lower access panel on the left or right side of the Dishwasher. If the water inlet valve is bad you have to replace it, also check the main water line for clogs/obstructions. If still the issue is not resolved then it’s a bad float switch and needs to be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

you have a sensor and it is restricted behind the bottom panel you see a rubber hose about 1/4'' in size remove and blow through it unless it a Bosh unit some how water gotten into the motor area this is cause by a plugged drain hose

hi there,

the drain valve of your dishwasher is maybe clogged or defective.there is alot of work on repairing this because the solenoid drain valve is at bottom of your dishwasher you may call a service dishwasher technician to uncloggged and repair this..this should be done by certified technician near your home.best regards

def replace .....time to put the old girl down ....whirlpool is a good choice ....or another bosh

The dishwasher is stuck in drain mode because there is water in a catch leak area underneath, it may have been caused by soap suds over flow or disposal backup. Remove bottom kick plate and vacuum out any water, then run dishwasher again and look for water leaks.

I think if u take the left side pannel off u will find the meatering tank clogged up which can not fill up the machine at diffrent levels.

the tech that came out may have pinched the drain hose when he put the dishwasher back in place. disconect drain hose from under sink. put dishwasher in cancel/drain mode see if water is coming out at a trickle if so, hose is probably pinched behind dishwasher
