Whirlpool Dishwasher Error Codes — Complete List

Whirlpool dishwashers report faults as paired numbers, shown as F#E# on models with a display. The guides here follow Whirlpool's own per-code help articles, from control and console faults (F1, F2, F6E1) through sensor, heating and wash-motor errors to the water codes: fill valve (F8), drain (F9), diverter (FA/F10) and the plain H2O no-water message.

• 1-1 (F1 E1) The control board detected one of its own relays stuck on — a long power-off clears the false alarms, while a genuinely welded relay means board-level repair.
• 6-4 (F6 E4) The overfill float switch — the machine's anti-flood backstop — is reading open, usually because the float is stuck or obstructed, occasionally because the inlet valve is dribbling water in when it should be shut.
• 1-2 (F1 E2, F1E2) F1E2 means the dishwasher's main control has logged a communication error — disconnect power for 30 seconds to reset it, and book service if the code returns.
• 2-1 (F2 E1, F2E1) F2E1 points to a stuck key or a console error on the control panel; cycling power for 30 seconds is the fix to try, and a repeat means the console needs professional attention.
• 2-2 (F2 E2, F2E2) A Whirlpool dishwasher showing F2E2 has a main control communication error, which a 30-second power disconnect sometimes clears and a technician must diagnose if it does not.
• 3-2 (F3 E2, F3E2) F3E2 indicates a problem with the thermistor or OWI sensor — the part that reads water temperature and clarity — so reset power for 30 seconds and have it serviced if the code persists.
• 4-2 (F4 E2, F4E2) F4E2 tells you the control has found a problem in the heating system; try a 30-second power reset, and leave any repair of the heater circuit to a technician.
• 4-3 (F4 E3, F4E3) F4E3 is Whirlpool's heating error code for dishwashers: reset the control by cutting power for 30 seconds, and schedule service if the error comes back.
• 6-1 (F6 E1, F6E1) F6E1 flags a user interface or main control error, so cycle power for 30 seconds and call for service if the code is still there afterwards.
• 6-3 (F6 E3, F6E3) F6E3 means the dishwasher has detected excessive suds — scoop out the foam, run an empty cycle with no detergent, and stop using anything but automatic-dishwasher detergent.
• 7-2 (F7 E2, F7E2) F7E2 reports a wash motor error; power-cycle the dishwasher for 30 seconds and schedule service if the code returns, because motor diagnosis is not a DIY job.
• 8-2 (F8 E2, F8E2) F8E2 is a fill valve electric error: check for leaks around the water inlet valve connection, power-cycle the dishwasher, and schedule service if the code returns.
• 8-4 (F8 E4, F8E4) F8E4 appears when the float switch in the drip tray under the tub is triggered — check the water connection and float switch on a new install, empty the tray, and press Cancel twice to clear it.
• 8-5 (F8 E5, F8E5) F8E5 means the fill valve is stuck open and water may keep entering the tub — turn off the water supply to the dishwasher, press Cancel once, keep the door shut, and arrange service.
• 9-1 (F9 E1, F9E1) F9E1 means the dishwasher is taking too long to drain — clean the filter, check the drain hose for kinks or clogs, and clear the sink disposer or air gap before restarting.
• 9-2 (F9 E2, F9E2) F9E2 is a drain motor error: rule out a blocked disposer or kinked drain hose, cycle power, and schedule service if the code returns.
• 10-4 (FA E4, FAE4, F10 E4, F10E4) FAE4, also shown as F10E4, is a diverter valve error; disconnect power for 30 seconds to reset the control and contact service if the code stays.
• 10-5 (FA E5, FAE5, F10 E5, F10E5) FAE5 or F10E5 signals a diverter leak — look for water under the dishwasher, make sure the water connections are secure, press Cancel twice, and schedule service if it comes back.
• H2O (H20, F8E1, 8-1) H2O on a Whirlpool dishwasher means it is not detecting water — make sure the supply valve is on and the supply hose is not kinked, then press Start so it can try to fill again.
• Clean Light Flashing (Clean Light Blinking, Blinking Clean Light) A flashing Clean light on a Whirlpool dishwasher is usually an error code: count the first set of flashes for the F number, wait for the short pause, then count the second set for the E number.
• Sanitize Light Flashing (Sani Light Flashing, Sani LED) A flashing Sanitize light means the dishwasher did not reach the temperature needed for sanitization, so the dishes were not sanitized — check your hot water reaches at least 120°F and avoid opening the door mid-cycle.
• Start/Resume Light Flashing (Start Light Flashing, All Lights Flashing, Start/Resume Blinking) A flashing Start/Resume light — or all cycle and option lights flashing — means the cycle or start-up was interrupted: press Start/Resume and push the door firmly closed within 3 seconds.
• Control Lock Light (Lock Light Flashing, Control Lock) If the lock light flashes three times when you press a button, Control Lock is on — press and hold the Control Lock button for 3 seconds to unlock.
• Rinse Only Light Flashing (Rinse Only Blinking) A rapidly flashing Rinse Only light on a portable dishwasher means multiple keys are stuck — press each key one at a time to release them, or press Cancel.
• Front Status Light (Status Light Blinking, Blue Light, Red Light, White Light) The front status light shows cycle progress — blue for washing, red for drying, white when complete — and a blinking light means the cycle has paused.
