Reading the code

Codes appear in the door display or status window; models without a display may use flashing option or status lights for power loss or door open, or a RINSE AGENT LOW light for rinse aid. To clear a code, close and latch the door, press START/CANCEL or CANCEL, then unplug the dishwasher for 3 minutes before trying a new cycle, and unplug before cleaning filters or checking a visible hose. 01-24, 1-199, HO or Hd, LOC and L0-L6 are status messages rather than failed parts.

Have the model number ready

The company will ask for it first. It's on a sticker or metal plate, usually in one of these spots:

Frigidaire dishwasher error codes

Current owner guides use i10 through iC0 fault codes, while many older electronic controls also show ER/CE, ER/uo, ER/uF, ER/ER, LO and PF readouts.

23 codes

CodeWhat it meansCheck firstUsually
i20 / i40 / iF0The control detected clogged filters, food soil in the sump or a restricted drain line, so the dishwasher did not drain correctly.Unplug the dishwasher, clean the filters and sump area you can reach from inside the tub, and check the visible drain hose under the sink for kinks.Often a home check
i30The dishwasher detected a leak or overflow of water in the bottom pan.Needs a technician because water in the base pan can involve an internal leak, valve, hose or level issue; unplug the dishwasher and stop running cycles.Usually a technician
i10The dishwasher detected a low fill, meaning it did not sense enough water entering the tub.Unplug the dishwasher, make sure the water shutoff valve is fully open, and check that the visible water supply line is not kinked.Often a home check
PFThe dishwasher detected a power loss or interruption; on some models without a display, certain option lights flashing indicate the same condition.Press START/CANCEL to clear the message, then start a new cycle after power is steady.Often a home check
CL / Cd / CLOSEThe door is open or not fully latched; on some models without a display, flashing status lights can mean the same door condition.Close the door firmly and check that racks, dishes or the gasket are not keeping the latch from engaging.Often a home check
HO / HdThe dishwasher is in heat delay or heater on mode while it brings the water up to the cycle temperature.Run hot water at the sink before starting a cycle, then allow the dishwasher time to heat the water.Often a home check
i50The control detected a problem with the drain motor or wash motor.Needs a technician because the drain or wash motor circuit is internal; press CANCEL and unplug for 3 minutes once, then stop if the code returns.Usually a technician
i60The control detected a problem with the water heating system.Needs a technician because the heater, thermostat, temperature sensor and wiring are internal; unplug for 3 minutes and retry once.Usually a technician
iC0The control detected an electronic control system fault.Needs a technician because the electronic control system needs diagnosis; unplug for 3 minutes and retry once.Usually a technician
ER / uoThe older electronic control detected that the vent will not close.Needs a technician because the dry vent and damper are internal; unplug for 3 minutes and retry once.Usually a technician
ER / uFThe older electronic control detected that the drying fan is not running or fan speed is not being sensed.Needs a technician because the dry fan, vent assembly or wiring is internal; unplug for 3 minutes and retry once.Usually a technician
ER / CEThe older electronic control detected a configuration error.Needs a technician because the control configuration or option setup must be checked at the control; unplug for 3 minutes and retry once.Usually a technician
ERThe older electronic control detected a switch failure.Needs a technician because the keypad or switch circuit needs testing; unplug for 3 minutes and wipe moisture from the control surface before retrying once.Usually a technician
LO / LowThe rinse aid level is low; on some models without a display, a RINSE AGENT LOW light means the same thing.Refill the rinse aid dispenser and make sure the cap is secure.Often a home check
LOCThe door or controls are locked, depending on the model.Use the model lock control, often holding DELAY START for 3 seconds or pressing DELAY START until loc clears on stainless tub models.Often a home check

Common questions about appliance repair

How do I reset a Frigidaire dishwasher code?

Press START/CANCEL or CANCEL, then unplug the dishwasher for 3 minutes before trying a new cycle. If a leak, motor, heater, vent, sensor or control code returns, have a technician diagnose it.

Why does i20, i40 or iF0 keep coming back?

Those codes point to draining, filters, the sump area or the drain hose. Unplug the dishwasher, clean the filters you can reach from inside the tub and check the visible drain hose for kinks, then have a technician check it if the code returns.

Why does my older Frigidaire show ER/uo, ER/uF or ER/CE instead of i codes?

Many older electronic controls used ER style readouts for vent, fan, switch and configuration faults. Newer owner guides often use i10 through iC0 for fill, drain, leak, motor, heat and control faults.

Is CL a broken latch?

Usually no. CL, Cd or CLOSE means the door is open or not fully latched, but if the door will not latch after checking racks and dishes, a technician should inspect the latch.

Still showing the problem after the checks?

Call and describe what you tried. You'll be connected with an independent repair company near you.
