We have an 11 year old dishwasher that wont drain. I have pulled the check valve and cleaned it, but the washer still fills with water. Reading help sites it seems like there might be something missing on my valve. Is there anything inside besides a rubber flap? Other than that, when running, it seems like there isn't enough pressure to evacuate the water, the drain line has water and air sloshing back and forth. The line is clear. The motor is running and spraying, but does seem to hum oddly. Any suggestions?
Answer Tony, Check and make sure the drain system and disposal are not clogged or restricted. The "flapper' is the only thing inside the check valve assembly. It should flip open when the dishwasher drains and remain closed when washing or off. You may want to disconnect the drain hose from the plumbing under the sink, fill the dishwasher, then drain it, to see if the water evacuates properly(less than 60 seconds). You most likely have a damaged drain impeller 675806 or something in the pump housing, and will need to dismantle the pump and check.
Water comes right out of the check valve when we start the dishwasher. Is there a pop out disk in the valve?
Answer Hello. Based on the information you provided, it sounds like the check valve 675238 needs to be replaced on the unit.
Hi, I noticed with the drain hose off, water leaks out of the check valve after the fill cycle. The tank water level will be low after the wash cycle and the heating element is still hot. Is this from a defective check valve? Thanks.
Answer Hello Bob,
The purpose of the check valve is to prevent the sink water from entering the dishwasher. The leak you are describing is going the opposite direction. The water should not leave the dishwasher if the drain line is properly elevated to the bottom of the countertop before connecting to the drain as the installation instructions direct. The issue you described sounds much more like a failing water valve 3384890.
I was trying to fix a drain problem and unscrewed the 4 screws that go through the "support, pump mounting" bushings. part number 14. I ended up screwing them back in, since I realized that I didn't need to unscrew them, but they don't really screw in that well and some of them seem to be stripped. Anyway, after clearing the drain check valve, and turning on the machine, it's leaking all over the place. I suspect that I broke a seal when I removed those 4 screws. What should I do? Also, do I need to have the spray arm re-attached before I test things out? Perhaps that's why it was leaking. Thanks! Mark
Answer Hello Mark,
Those screws thread into the plastic pump housing. They are important and the unit will leak profusely if not properly tightened. Since the holes they thread into are stripped, this unit cannot be repaired since the pump assembly and its' individual components, I'm sorry to say, are no longer available.
