Bosch Dishwasher Drain problem

2 yr. old Bosch Dishwasher (SHE46) does not drain all the way about a third of the time. Sometimes does not drain at all. Most of the time it drains just fine. Hose is clear. nothing clogged around the impeller. Hose is connected to the garbage disposal & elevated 20'' above floor per directions.

Any suggestions?

Thanks.

    I have a 1995 Bosch Dishwasher that I have cleaned thoroughly and am noticing that it continually drains EXTREMELY slow. I have poured white vinegar in the drain - am wondering if I should use some kind of drain cleaner, or if the dishwasher has run it's course and is ready to be replaced.....

Bosch dishwasher runs continuously


I would call Bosch with you.re model and serial number, they have had a recall on your model for the control board and that sounds like it may be your problem, if it is under recall Bosch will send someone out at no charge to install a new board (800) 856-9226

Hi We have a 1 yr old Bosch dishwasher SGS45C02GB-06. It's stopped working for the second time in a year. It stopped mid-cycle and the water is not draining away or being pumped away; although you can...


Did you install the high-loop for the drain hose? If not, you need to pull out the dishwasher and make sure that the hose is not lying below the pump at the bottom of the dishwasher. This will usually fix this problem.

My Bosch dishwasher is only 2 yrs old and for the following two nights does not want to pump out the water. If I drain it, it sometimes starts the cycle and sometimes not?


If no warning lights show up, then it is a matter of finding if the outlet is blocked somewhere. I am assuming the fact you can drain it manually means the pump is ok. Perhaps some sensor which is covered in muck.

I would start by cleaning the filters at the base and then running the unit with a dishwasher cleaning kit (without dishes in it). Finish cleaning kit is quite good and the instructions are on the pack.

By the way these units normally have a 2 to 3 year warranty on some parts. I am assuming you have the proof of purchase so that you can call the Bosch support guys.

Water is puddeling on the bottom of my 18 yr. old GE dishwasher


HI. check the following areas for faults.

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Bosch Dishwasher SHV4303UC - Does not drain.


Try looking for slithers of glass etc under the impeller. Remove the sump covers (filters) and look into the bottom. There will probably be a small cover held down by a screw. Under this is the impeller. Roll up a hand towel into a cigarette shape and slide this under the impeller - that should clear anything out.

Bosch Dishwasher wont drain

Bosch SHU43


Sounds like the control module is out -- cost about $100 (I am on my third). I got a "lifetime" warranty when buying my second one. If you are handy, you can replace it yourself. You can call Bosch to confirm this (I did). It mounts inside the door. Mine is a BOSCH 5316.

The draining problem may mean a clogged drain hose -- you have to check it all the way back to either the main drain or the garbage disposal (if you have one). This may be what forced off the impeller wheel.
