My Bosch SHU4302UC/06 is running for a LONG LONG Time...These problems seemed to have started after a house drainage problem occurred. Debris from the drainage problem could have backup into the dishwasher. The cycle takes 1.5 hours and water is left in the bottom.
There seems to be TONS more water that used during the wash cycle as well. Any ideas?
Hi,
You could try running the machine with the drain hose leading to a large bucket. If it works OK in this situation then the blockage will be most likely where the drain hose joins the house drainage system - often at a junction under the kitchen sink. With the drain hose disconnected you should be able to see the blockage and clear it with a suitable pointy tool.
Let me know if this sorts it. Thanks, D.
Hi again,
I'm thinking there could be some debris in the hose itself, near to the machine or even partly clogging the pump. You might be able to clear it by running a cycle with no dishes but plenty detergent (or proprietory dishwasher cleaner) and when it starts to pump out get the drain hose really low to the ground into a bowl so there is minimal resistance to the water flow. Failing that you might need to turn the machine over and remove the hoses near the pump to get any heavy grit out of them.
Hope this helps you a bit more. D

I ran the hose to the sink. The drainage is definitely an issue. BUT their is still some water left in the bottom of the unit when the cycle is complete. Any ideas?
our dishwasher takes forever! The counter on the front starts at 99 and counts down, but takes over 3 hours to do so.
Our old dishwasher took less than an hour! what can I do?
