Resetting the control board on a Frigidaire Dishwasher Professional Series requires a timed power cycle followed by a button sequence. Owners complete this process to clear stored faults and restore normal operation without parts replacement.
The method works on most units that display persistent error lights after a cycle interruption. Follow each step in order to avoid triggering new codes during the procedure. This approach resolves the majority of control board glitches reported on the Professional Series models.
Frigidaire Professional Series Reset Supplies List
Owners need a few basic items to complete the reset safely on the Frigidaire Dishwasher Professional Series. These supplies prevent accidental damage during power disconnection and allow accurate timing of the button sequence. Proper preparation reduces the chance of incomplete resets that leave error codes active. The list below covers everything required for the full procedure.
| Item | Purpose |
|---|---|
| Voltage tester | Confirm power is off at the outlet |
| Timer or stopwatch | Track exact hold times during sequence |
| Dry cloth | Wipe control panel after reset |
| Multimeter | Check continuity on door switch if needed later |
Prepare Frigidaire Professional Series Safely
The Frigidaire Dishwasher Professional Series sits on a dedicated circuit that must be isolated before any reset attempt. Disconnecting power first protects both the user and the electronic board from surges during the procedure. Clear the area around the unit to allow full access to the lower kick panel and power cord. Verify the dishwasher is empty so no water remains that could leak during testing later. These steps establish a controlled environment for the sequence that follows.
Frigidaire Professional Series Power Button Reset Sequence
The reset sequence on the Frigidaire Dishwasher Professional Series uses a precise combination of power removal and button presses. Start by locating the power cord and pulling it from the outlet. Wait exactly two minutes for residual charge to drain from the board. Reconnect power then press and hold the start button for five seconds. Release and immediately press the cancel button three times in quick succession. The control panel lights should flash once to confirm the board has cleared stored data.
Disconnect power cord from the wall outlet before touching any buttons. Press start button firmly and count five full seconds.
Cycle cancel button three times without pausing between presses. Observe the panel for the single flash that signals completion.
Frigidaire Professional Series Recurring Error Checks
Error codes on the Frigidaire Dishwasher Professional Series often return if the root cause remains unaddressed after the board reset. Check the door latch first because misalignment prevents proper cycle start and recreates faults. Inspect the drain hose for kinks that trigger drainage errors even after the board clears. Run a short diagnostic cycle to confirm whether new codes appear within the first ten minutes. Persistent codes after these checks point to a failing sensor rather than the board itself.
Frigidaire Professional Series Normal Wash Test Cycle
A full test cycle verifies that the reset on the Frigidaire Dishwasher Professional Series restored normal function. Select the normal wash option and start the unit with no dishes loaded. Listen for the fill valve and drain pump to confirm both activate at the correct times. Monitor the control panel throughout to ensure no lights reappear mid-cycle. Complete the entire cycle and note the final status light before loading dishes for regular use.
Frigidaire Professional Series Cycle Verification Test
Owners confirm success when the Frigidaire Dishwasher Professional Series completes cycles without error lights for three consecutive runs. Record any codes that appear during this period for further diagnosis if needed. This final verification step ensures the board reset addressed the original fault rather than masking it temporarily.
