Frigidaire Dishwasher Er Error Code: Causes & Fix

What is the Frigidaire Dishwasher Er error?#

Er is the panel telling you it has lost a clean read of the touchpad — the button membrane is misbehaving, and nine times out of ten the culprit is simply moisture that has wicked into the pad overlay. Before you think about parts, kill power at the breaker for a minute and leave the door cracked open for an hour so the trapped steam can escape the console. If the pads come back to life, you never had a broken part at all.

Er on a Frigidaire Dishwasher: likely causes and repair cost#

On a Frigidaire Dishwasher, the Er code signals: membrane switch error.

Typical professional repair: $100–$275 · Difficulty: moderate · usually a technician job

Symptoms that often accompany Er: Pads go dead and ignore presses; The unit beeps on and on with no input; Selections fire on their own from stray contacts

Technician diagnostic sequence for Er:

1. This generic error on the panel almost always traces to damp getting into the touch strip, so treat drying it out as the primary repair rather than reaching for parts
2. Drop power at the breaker for a minute to let a merely-damp membrane recover, then leave the door cracked open an hour so the trapped steam can escape the console
3. Walk each pad through its travel to flush any one that is physically stuck, and wipe the seams where grease and moisture collect behind the buttons
4. If it keeps returning after every wash, the drying vent is aiming steam straight at the controls — that chronic soaking, not a one-time splash, is what eventually kills the overlay or the board

Parts a technician may check or replace: control panel overlay; control board

Field note: Nine times in ten this clears simply by drying the console: run it empty with the door ajar for an hour and the damp membrane comes back to life. A version that returns after every single cycle is a venting problem steering steam onto the panel, and fixing the vent path is what makes the repair stick.

How to troubleshoot the Er error yourself#

Start with the free repair, because this fault is far more often damp than dead electronics. Trip the breaker to the dishwasher for a full minute, then prop the door open for an hour so the console can dry out from the inside. While it is off, walk each button through its travel to free any pad that is physically stuck, and wipe the greasy seams where moisture collects behind the overlay. Bring the power back and try a cycle. If Er returns after every single wash rather than clearing once, the drying vent is steering steam straight at the controls — that chronic soaking is a job for a technician, who will reroute the vent path and, if the overlay or console board is already water-damaged, renew it. Anything involving opening the door panel and metering the board is where a homeowner should stop.

Is the Frigidaire Dishwasher Er error worth fixing?#

This is one of the cheaper Frigidaire faults to make peace with, and often it costs nothing at all — a dry-out clears most Er cases without a single part. When it does need a professional, a control panel overlay or console board repair runs $100 to $275, which is a small fraction of a new dishwasher and easily worth doing on a machine that is otherwise washing well. I only steer people toward replacement when the console has been soaked repeatedly and other systems are aging alongside it; a one-off damp panel on a sound dishwasher is always worth the fix.
