KitchenAid dishwasher not draining is a known issue affecting KDTM404K series. Our technicians specialize in KitchenAid-specific diagnostics and repair.
KitchenAid dishwasher not draining is typically caused by clogged drain hose or failed drain pump. KitchenAid-specific factor: shared whirlpool platform — chopper blade jam and drain solenoid failures identical to whirlpool/maytag. Repair costs $100-$250 with free diagnostic and 90-day warranty.
Shared Whirlpool platform — chopper blade jam and drain solenoid failures identical to Whirlpool/Maytag
Disposal knockout plug not removed during kitchen remodel installation — blocks drain path entirely
Check ball valve stuck from grease and mineral accumulation — water sits in sump between cycles
Drain motor/pump assembly burnout from running against blocked sump
Third-rack models have longer drain paths that are more susceptible to restriction
Other KitchenAid models may also be affected. Book a free diagnostic for confirmation.
Seeing one of these codes? It likely indicates not draining.
KitchenAid dishwashers are premium installations in Bay Area remodeled kitchens — the KDTM404K with its third rack is the most popular model. Bay Area drain failures frequently trace to the disposal knockout plug oversight during remodel, identical to Whirlpool. In older San Francisco homes, drain hose routing without proper air gap compliance creates chronic backflow. KitchenAid uses the same Whirlpool drain system so all diagnostics and parts cross-reference.
Remove lower spray arm and cylindrical filter — inspect chopper blade for food debris jam and mineral scale
Check disposal knockout plug: disconnect drain hose at disposal, look inside inlet with flashlight — blocked port means plug was not removed
Run diagnostic (same as Whirlpool): press Heated Dry + Normal + Heated Dry + Normal within 6 seconds — advance to drain test step
Test drain solenoid with multimeter: should read 30-40 ohms; infinite reading means coil is open requiring replacement
KitchenAid dishwasher drain repairs follow Whirlpool procedures using identical parts. The technician inspects the chopper blade area and filter assembly first. Disposal knockout plug removal is a 5-minute fix when identified. Drain solenoid or pump motor replacement requires pulling the unit forward for underneath access — about 30-45 minutes. The technician verifies air gap compliance and recommends monthly hot wash cycles for Sacramento hard water homes.

“My exprience with Easy Bear was absolutely superior from the beginning. I had a Subzero decide to quit. Daniel assessed the issue immediately, ordered the required new " motherboard" and had it installed within three days. My prior replacement of said part took 5 months during Covid. Daniel is smart, professional, clearly knows his trade . I most definitely will use Easy Bear in the future.”

“Daniel the technician came to diagnose what's causing our washing machine water overflowing. He didn't actually have to do anything to solve the issue, because as soon as he turned it back on, it began to work properly, but explained what the probable cause was. He was sincere and clear on the matter related to the situation. I wasn't charged for his visit as I was told ahead of time. Stanislav was also cordial arranging for all of the process. I will call them next time I need an appliance service without hesitation.”
