47 error codes

Code	Meaning	Severity	Difficulty
4-3	4 blinks, pause, 3 blinks - water heating fault on pre-2010 Whirlpool dishwashers using blink-code diagnostics instead of alphanumeric display codes moderatebeginner	moderate	beginner
BEEPING	Repeated beeping from the dishwasher after or during a cycle - end-of-cycle notification, error code alert, door-open warning, or control board communication fault lowbeginner	low	beginner
CLEAN-BLINK	The Clean light is flashing after a cycle -- the sanitize or cycle completion condition was not properly met, or the cycle was interrupted lowbeginner	low	beginner
CONTROL-LOCK	Control Lock (child lock) is engaged on the control panel - all buttons except Power are disabled to prevent accidental operation lowbeginner	low	beginner
DIAG-MODE	Service diagnostic mode -- a hidden self-test sequence that activates all components and displays stored fault codes not shown during normal operation lowbeginner	low	beginner
DOOR-WONT-CLOSE	The dishwasher door will not latch closed - preventing any cycle from starting, caused by a misaligned latch strike, broken latch assembly, or overloaded bottom rack preventing door swing moderatebeginner	moderate	beginner
E1 F1	A relay on the main control board has failed - stuck open or closed - preventing a critical circuit from being switched correctly highadvanced	high	advanced
E1 F6	Water inlet fault - same fault as F6 E1 displayed in reversed code order on certain model variants moderatebeginner	moderate	beginner
E1 F9	Drain cycle did not complete within the allowed time -- the pump ran but water level failed to drop fast enough moderatebeginner	moderate	beginner
E2 F2	Water entering or inside the dishwasher did not reach the minimum expected temperature within the heating window -- could indicate a cold supply issue or a failed heating assembly moderateintermediate	moderate	intermediate
E4	The NTC thermistor (water temperature sensor) is reading outside the expected resistance range -- either an open circuit, shorted sensor, or actual water temperature extreme moderateintermediate	moderate	intermediate
F4 E3	The thermal protection fuse has tripped or blown due to an overheat condition - the dishwasher shuts down to prevent damage to the tub or surrounding cabinetry highintermediate	high	intermediate
F6 E1	Water did not reach the required fill level within the allotted time - inlet valve failed to open, supply pressure is too low, or the valve screen is blocked moderatebeginner	moderate	beginner
F7 E1	The heating element circuit has failed - element burned out, heater relay on the control board has failed, or the thermistor is reporting no temperature rise highintermediate	high	intermediate
F8	The control board lost communication with the wash motor control circuit - a signal-level fault rather than a full motor hardware failure highintermediate	high	intermediate
F8 E4	Wash motor circuit fault -- the motor failed to start, drew a current spike, or the motor control relay on the board has failed highintermediate	high	intermediate
F9 E1	Drain cycle exceeded its allowed time limit -- pump ran but water did not evacuate the tub fast enough moderatebeginner	moderate	beginner
FA E4	The door latch or door switch is sending an incorrect signal to the motor control circuit - the dishwasher interprets the door as open or latched improperly while a motor command is active moderateintermediate	moderate	intermediate
H2O	The fill sensor or float switch did not register water entering the tub - the inlet valve may not have opened or the sensor failed to detect the fill moderatebeginner	moderate	beginner

LIGHTS-FLASH	Multiple control panel lights flashing in a pattern -- used by older models as the diagnostic code system, or indicating a fault condition on newer models lowbeginner	low	beginner
NOISE	Causes and Fixes mediumintermediate	medium	intermediate
NORMAL-BLINK	The Normal cycle button or indicator is flashing - typically indicates a cycle was interrupted, a fault was detected during a Normal cycle, or the control board is in a fault-signaling state lowbeginner	low	beginner
NOT-CLEANING	Dishes coming out dirty, with food residue, or with a film - caused by spray arm blockage, detergent issues, clogged filter, or inadequate water temperature lowbeginner	low	beginner

NOT-DRYING	A Whirlpool dishwasher not drying dishes has specific causes related to Whirlpool's design and component choices. mediumintermediate	medium	intermediate
NOT-FILLING	The dishwasher starts a cycle but no water enters the tub -- inlet valve fault, supply issue, or float switch stuck moderatebeginner	moderate	beginner
NOT-FILLING	Inlet Valve, Float, and Supply Fixes mediumintermediate	medium	intermediate
NOT-HEATING	The dishwasher completes cycles but water stays cold and dishes come out wet - heating element, thermostat, or control board heater relay fault moderateintermediate	moderate	intermediate
NOT-SPINNING	The upper or lower spray arms are not rotating during the wash cycle, resulting in dishes that come out with food still on them or cloudy with detergent residue. Water is present in the tub but is not being distributed. mediumbeginner	medium	beginner
NOT-SPINNING	Spray arms are stationary during the wash cycle - blocked by a dish, clogged jet holes, or insufficient water pressure from the wash motor lowbeginner	low	beginner
NOT-SPRAYING	Water enters the tub but the spray arms are not rotating and spraying - caused by blocked spray arm holes, a failed wash motor, or the spray arms being physically obstructed moderatebeginner	moderate	beginner
NOT-STARTING	Dishwasher does not begin a cycle when Start is pressed - could be door latch, control lock, power supply, or delayed start setting lowbeginner	low	beginner
QUIET-PARTNER	The Whirlpool Quiet Partner series refers to noise-rated dishwasher lines from Quiet Partner I through Quiet Partner V - this is not an error code but a product line identifier lowbeginner	low	beginner

SANITIZE-BLINK	The Sanitize indicator is flashing after a cycle - the water did not reach or maintain the required 150F sanitize temperature for the NSF-required duration lowbeginner	low	beginner
SELF-START	The dishwasher starts a cycle without being intentionally activated - caused by Delay Start timer expiring, a stuck relay on the control board, or a malfunctioning touchpad lowbeginner	low	beginner
SMELL	Unpleasant odors from the dishwasher tub - caused by food debris in the filter, biofilm in the sump, mold in the door gasket, or a drain that is not clearing fully lowbeginner	low	beginner
START-BLINK	The Start or Start/Pause button is flashing - indicates the cycle is paused, waiting for door closure, or a fault has paused operation and the unit is requesting a user response lowbeginner	low	beginner
STOPS-MID-CYCLE	The dishwasher halts partway through a wash, rinse, or dry cycle - sometimes with a blinking light, sometimes silently. The machine has detected a fault condition or lost power mid-run and entered a pause state. mediumbeginner	medium	beginner
