Customer Questions and Answers for Dishwasher Check Valve by Bosch

No special way to get that but you may have to remove the dishwasher and disassemble it.

That is possible but I would double-check the entire installation to be sure the hoses are installed properly as well.

David, if the water is at the bottom of the sump where the aqua sensor is, this is normal as the drain pump is not going to be able to pump all of the water out. The drain pump utilizes water to push water through the drain, which causes a little bit to be left in the sump assembly.

Shilpa, the drain of the model provided does utilize a check valve 00611320 at the sump where the drain hose would connect into the dishwasher.

Negel, Check and see if the main control is sending voltage to the drain pump. If your getting 120 vac to the drain pump them your pump is faulty or you have a clog may be in the drain line. And if valve continuously fills just curious how you are stopping that. Do you have to turn off the water supply? Possible stuck relay on the control or the solenoid on the valve is stuck open. With both issues, I'm leaning more to control but I would test these things.

Hello Roger, If the drain pump is getting 120Vac when it should be draining but the pump is not running, make sure nothing is in the impeller. If nothing is in there preventing the pump from running and the filters are clean and there are no clogs, you will need to replace the drain pump 00642239. (This is also if the garbage disposer has not been replaced and the knockout in it has not been knocked out.) If you are not getting 120Vac to the drain pump, you may need to replace the control board 00647474. IMPORTANT NOTE: The manufacturer has a note by this part stating that the customer should contact them at 1-800-944-2904 to make sure this is the correct part number for the model number on the units' I.D. tag.

Will, The non return valve on this unit would be part number 00165262. You may also want to try to run a clean cycle on the unit which you could use glisten dishwasher cleaner W10549845 to do this.

Bob, The non return valve 00165262 would be located on the out port of the sump assembly where the drain hose would connect to the sump. If the non return valve is not there then it would need to be replaced. You will also want to check the impeller on the drain to make sure that the impeller is not damaged.

Hello Karen. If there is water in the base, you need to repair the leak in the unit. If there is no water in the base, you need to check and see if the float is stuck in the unit.

Hello Jody! Part number 00165262 is the backflo preventer, aka the non-return valve. You may want to check the pump for this part to make sure it doesn't damage any of the inside parts. Thanks.
