F8E4: Overfill / float switch open
- Brand
- Whirlpool
- Appliance
- Dishwasher
- Code
- F8E4
- Documented meaning
- Overfill / float switch open
- Applies to
- 25 Whirlpool models on 3 platforms
- Can you keep using it?
- No — stop and have it checked
F8E4 means the overfill float switch has opened, which on these models usually means water has collected in the leak pan under the dishwasher.
What the dishwasher is detecting
A foam float in a pan under the tub opens its switch when water collects there. The control stops filling, drains, and stores this code to prevent flooding.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented Water in the leak pan under the dishwasher from a leak, an overfill or suds.
- Documented The overfill switch unplugged or its float stuck in the up position.
- Documented A drain problem; the documentation sends the technician to the drain codes.
- Documented A fill valve stuck open, or the control's fill valve switching part shorted.
- Documented A dishwasher that is not level, so water surges into the overfill funnels during the cycle.
- Documented Opening and closing the door quickly while the dishwasher is hot, which can push droplets into the funnels.
- Documented Too many suds.
Safe checks you can make
- Look along the floor in front of the dishwasher and in the cabinet under the sink for water, and mention anything you find to the technician.
- Use only automatic-dishwasher detergent. Hand dish soap, even a small squirt, makes heavy suds that a dishwasher cannot handle; if that happened, run a rinse with the door shut a few times to clear it.
- If you open the door while the dishwasher is hot, leave it open a few minutes before closing it again.
- If water keeps entering the tub with the dishwasher off, turn off its water supply valve under the sink and switch off its breaker.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Removes the lower access panel to check the leak pan and float switch.
- Finds and corrects the source of the water; the documentation warns the code will return if the root cause is not fixed.
- Checks the dishwasher for level and reviews drain and fill codes in the history.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher water inlet valve replacement | $180–$360 | Light |
| Dishwasher drain pump replacement | $180–$400 | Moderate |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Stop using the dishwasher until the cause is found. An overfill condition can mean water on the floor and in the cabinetry. If water keeps coming in, shut off the supply valve and the breaker.

F8E4: Draining: drain motor electrical problem
- Brand
- Whirlpool
- Appliance
- Dishwasher
- Code
- F8E4
- Documented meaning
- Draining: drain motor electrical problem
- Applies to
- 19 Whirlpool models on 1 platform
- Can you keep using it?
- With caution
F8E4 means the control found an electrical fault in the drain pump circuit: the pump motor, its wiring, its fuse on the control or the control's drive.
What the dishwasher is detecting
The control checks the drain pump circuit when it calls for draining. An open motor winding, a blown fuse, a pump locked by debris or a failed drive circuit sets this code.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A loose connection in the drain motor circuit or an open drain motor winding.
- Documented Debris jammed in the drain pump impeller (listed on later platforms).
- Documented An open fuse on the control that feeds the drain motor.
- Documented A failed drain motor drive circuit on the control.
Safe checks you can make
- If your model has a removable filter in the bottom of the tub (the owner's manual shows how to twist it out), take it out, rinse it under the faucet and lock it fully back in place.
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the drain motor and every connection in its circuit with power off.
- Removes the pump to clear debris from the impeller if needed.
- Checks the control fuse for the drain circuit before suspecting the control.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher drain pump replacement | $180–$400 | Moderate |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The dishwasher may not drain. Do not keep restarting cycles with water in the tub; schedule service.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F8E4 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
