Counted from our technicians' notes on 87 Whirlpool dishwasher service calls.
Water on the kitchen floor
A leak at the front of the dishwasher has a few common sources. Hand dish soap makes suds that push out past the door. A dishwasher that isn't level won't let the door seal squarely. And the door gasket itself may be cracked or crusted with food. Water under the middle or back is a different story. That points to a loose drain or supply connection, a worn motor or pump seal, or an inlet valve that's stuck open.
Dishes still dirty after a full cycle
Look at the filter and spray arms first. A packed filter, or a spray arm with plugged holes, can't move enough water. When both are clean and the wash still sounds weak, the circulation pump or motor may be on its way out.
A puddle left in the tub
New installs hooked to a garbage disposer sometimes still have the disposer's knockout plug in place. On an older setup, check for a clog in the disposer or the drain path. Once that's clear, the drain pump is next.
Why everything comes out wet
Start with the rinse aid. When it's low or empty, dishes stay wet. Feel the tub right after a Heated Dry cycle. A tub that isn't warm suggests the heating element or its circuit has failed.
What to try at the sink first
- Rinse the filters with a soft brush, since a wire brush can damage them. To get them out, twist the upper assembly a quarter turn counterclockwise and lift, then slide the lower filter toward you.
- Top off the rinse aid and pick Heated Dry.
- Let the kitchen faucet go until the water turns hot, 30 to 60 seconds, before you hit start.
- Use dishwasher detergent only, since dish soap makes suds that push water out the door.
- Run the disposer before you start the dishwasher.
- To reset it, switch the breaker off for about a minute.
Our water is hard on dishwashers
Much of Minnesota, Wisconsin and Southwest Florida has mineral-heavy water. With hard water, Whirlpool suggests turning the rinse-aid dial up. The minerals also leave calcium on the filter, so look it over more closely when you clean it.
Blinking lights, not codes
Most Whirlpool dishwashers signal faults with blinking lights, not a code readout, and the same pattern can mean different things on different models. Have your model number ready and we can interpret it for you. Open the door and you'll find the tag on the tub frame's left edge.
