Questions & Answers

For Frigidaire Main Control Board (Part Number: OEM18981690)

Ron, you may want to check the turbidity sensor located in the sump assembly under the filter screen. The turbidity sensor can have a build up on it that can cause the dishwasher to sense heavy water soil and cause it to have long wash times.

Darlene, the component responsible for the LED indicators would be the user interface panel [154791806]. If the user panel was not operating at all, then you would look towards the main control, but as it is the LED indicator, it would be the panel itself.

Jim, Based on the information you will want to first check the door switches to make sure that they are good and if they check ok then the control board would be the issue.

Shawn, This would be a control panel that is faulty and would be part number 807545704 and can be purchased at appliancepartspros.com or by calling 877-477-7278. The ER Clean S would indicate a stuck key on the keypad.

Kendra, A model number of the dishwasher would be a big help, but, if you still have the PF code, first check for proper connections and power supply (120 VAC) at the junction box behind the lower access panel, on the front frame of the dishwasher. Remove the door panels and check the door switch circuits and wiring. If all's OK, replace the control panel / key pad assembly first. You probably have a problem in the circuitry, and the inputs from the keys aren't communicating with the control board.

John for Model Number PLD2850RDC2

When I start a wash cycle with my dishwasher the display normally shows a number, like 86 (indicating the length of cycle in minutes) the display counts down from 86 down to 0 when the cycle ends. Currently, when I start a cycle, the display shows 1. The dishwasher will run and the display counts upwards to 10 and then the dishwasher stops and the display clears. While running, the key pad does not respond to any commands (ie. Cancel). I’ve shut the power off at the breaker for extended periods, but it doesn’t fix the problem. Is this a touch pad, control board or control panel issue?

1 Answer

Chris, There would not be just an F code but could be a PF or a UF. Would try hitting cancel and see if the code disappears and if it does not then check the vent motor as it may be causing the issue.

Thomas, normally a PF represents a power failure and can be cleared out by pressing the cancel button, if it continues, you may need to replace the main control, 5304514670
