"PF" flashes om control panel and alarm beeps continually when plugged
pf flashes in display, alarm beeps continually if plugged in to outlet
"@jmark for a PF code to display it means that voltage was lost to the control. From what you are saying it sounds like the problem could be a loose connection at the control board. There are two connectors on the control board and two wires that could cause this problem. The two wires on the P9 and P8 connector are black and white. Check those to make sure that they are properly seated and teh pins are in good order.
You of course also want to check that you have proper voltages on your AC outlet. You need 220 V on the outlet. check your fuses to make sure that they are okay. You also want to make sure that the machine vents the hot air properly. If there is any blockage in the hot air outlet, it is possible (but less likely in your case) that it heats up a thermistor which then reports it as a PF. Let us know what you find"
