Whirlpool dishwasher repair, from the cup out
Tablet still sitting in the cup? Whirlpool says a dispenser that was damp when you loaded it can hold detergent back, and an upper rack in its lowest slot can stop the lid opening. Check both before booking us on Oahu.

Why does the tablet stay in a Whirlpool cup?
Most often the lid never opened or the water never got hot. Whirlpool's list is short: detergent that clumped after sitting open to the air, a cycle that was cut off early, a pan handle or wooden spoon in front of the lid, and a cup that was damp when filled. Run the kitchen tap hot before starting. Keep detergent sealed in a cool, dry spot, which takes some doing in a humid Oahu kitchen. If the lid still sticks with all that right, the latch or wash system needs a look.

Whirlpool dishwasher codes that point past the reset
Whirlpool's first step for nearly all of these is the same: power off for 30 seconds at the plug or breaker. These are the ones that keep coming back.
| Code | Whirlpool names | Owner check | Repair if it returns | Read next |
|---|---|---|---|---|
| F9 E1 | Long drain | Rinse the filter, look for a kinked hose, and on a new install make sure the disposer knockout plug is out | Drain pump or a blockage further down | Dishwasher not draining |
| F6 E4 | Water float switch | Check the machine is level; a tilt can trip the overfill float | Float or switch | Dishwasher leaking |
| F3 E2 | Thermistor or OWI sensor | Power reset only | Sensor replacement | Dishes not clean |
| FA E4 or F10 E4 | Diverter valve | Power reset only | Diverter repair | Dishwasher repair |
| F2 E1 | A stuck key or console fault | Wipe the panel, then reset | Console or control | Dishwasher will not start |
Has Whirlpool ever recalled its dishwashers?
Yes, twice in notices worth checking on an older unit. In May 1996 about 500,000 Whirlpool and Kenmore machines were recalled because door latch wiring could overheat and catch fire; the Whirlpool models start DU8, DP8, DU9 or GDP and were sold from June 1991 to October 1992. In February 2005 it was under-counter plastic tall tub models starting DU1, DUL, GU1, GU2 or GU6, with serials FR2200000 to FR2499999, over wash motor wiring. Read the tag on the tub edge with the door open.
