Whirlpool Dishwasher Error Codes Explained

Whirlpool dishwashers display fault codes when the control board detects something outside normal parameters. These codes appear on the display or as a series of blinking lights depending on your model. Here's what the most common Whirlpool dishwasher error codes mean and how to address them.

How to Access and Clear Codes

On most Whirlpool dishwashers, error codes display automatically when a fault occurs. To enter service mode on many models, press Heated Dry, Normal, Heated Dry, Normal in quick succession. The display will cycle through any stored fault codes. Always try a power reset first (cancel the cycle and unplug for 60 seconds) before acting on a code.

Common Whirlpool Dishwasher Error Codes

F1E1 — Control Board Fault

The main electronic control board has detected an internal fault. Try a power reset first. If the code returns, the control board likely needs replacement — a technician repair.

F2E1 — Keypad / User Interface Fault

One or more buttons on the control panel are not responding correctly. Check for anything pressing against the panel surface. If the panel appears physically fine, the user interface board may need replacement.

F3E1 — Temperature Sensor Fault

The water temperature sensor (NTC thermistor) is reading outside the expected range or has failed. The dishwasher may not heat water correctly. Thermistor replacement is typically a straightforward repair.

F3E2 — High-Limit Thermostat Fault

The high-limit thermostat has tripped or failed. This prevents the heating element from operating. Check for a genuine overheating condition (blocked filter, improper loading) before replacing the thermostat.

F6E1 / F6E2 — Water Inlet Fault

The dishwasher is having trouble filling with water. Check that the water supply valve is fully open, the inlet hose isn't kinked, and the fine mesh screen inside the inlet valve connection isn't clogged with mineral deposits. If supply is confirmed good, the inlet valve itself may need replacement.

F7E1 — Heating Circuit Fault

The heating element is not operating correctly. The dishwasher won't heat water for cleaning or drying. Heating element testing and replacement is a technician repair, part of our Whirlpool dishwasher repair.

F8E1 — Long Drain (Drain Fault)

The dishwasher is taking longer than expected to drain. Check the drain hose for kinks, clean the filter, confirm the high loop in the drain hose is intact, and check the garbage disposal connection. If the drain path is clear, the drain pump may be failing.

F8E4 — Drain Pump Fault

The drain pump has a fault — it may be blocked, seized, or failed. Remove the filter and inspect the pump area for foreign objects. If clear, the pump motor needs professional testing.

F9E1 — Dispenser Circuit Fault

The detergent or rinse aid dispenser system has a fault. The dispenser motor or wiring may need replacement. Confirm the dispenser door moves freely and isn't jammed by a rack item first.

FAE1 — Overflow Fault

The dishwasher has detected a potential overflow condition. Similar to Bosch's E15, this typically means water is in the base pan or the float switch (which monitors water level) is stuck in the triggered position. Check for a leak and inspect the float switch at the bottom of the tub.
