F8E4 — Leak / Float Switch Tripped
The float switch under the unit trips when water gets into the base — usually a diverter seal or a cracked spray-arm feed tube.
The fix: We find the actual leak, not just reset the float.

F8E4 / leaking. The float switch under the unit trips when water gets into the base — same concept as Bosch's E15. Usually a diverter seal or a cracked spray-arm feed tube. We find the leak, not just reset the float.
Won't drain. Drain pump failure is the classic Whirlpool issue after 5–6 years — the pump gets weak, then quits. Twenty-minute part swap once diagnosed.
Door latch failures. The door won't latch, or the unit stops mid-cycle when the door "pops." The latch assembly wears out — cheap part, quick fix.
Control board failures. If the unit is dead with power at the outlet, or cycles behave erratically, the board is suspect. We test before replacing — boards aren't cheap enough to guess on.
Cloudy/filmy dishes. Often the heating element underperforming (Whirlpool elements are a wear item) combined with the hard water found across much of Washington State. Element + descale, problem gone.

Here's the rule we use: if the repair costs less than 50% of a new dishwasher's price — and the machine is under 8–10 years old with a solid tub and racks — repair is almost always the smart money. Whirlpool parts are inexpensive and the machines are simple, so a $150–$250 repair commonly buys 3–5 more years. On the fence? Read our honest repair-vs-replace guide (the 50% rule explained), or call (253) 549-3002 and we'll give you the honest math before you spend a dollar.
