Re: Whirlpool adp5966 dishwaher F3 error
Hi,
F3………1) Heats the water too slowly.
2) No heat
usually takes 29 minutes to fault to F3
I think this dishwasher is the optical sensor one which means any of these can be faulty.Sensor…4812 271 28459 Could just want cleaning(the lens surface gets grubby)
heater(tube type) 4812 259 28684 Check resistance and insulation
base control card…….481221478704 .. inspect for edge connections and blown tracs on the board(indicating failure elsewhere in the dishwaser)
even if you are extremely confident in your abilities I would recommend you get an experienced engineer to this, it could well save you money because wont need all three parts.ted
Re: Whirlpool adp5966 dishwaher F3 error
Whirlpool result for error code F3.
F3 indicates a Heating System Defect.
Heater or relay on control board defect.
Also check cabling.These machines are notorious for bad connections.
The control board can also suffer from corrupt software. The eprom can be reprogrammed with the right equipment.
Re: Whirlpool adp5966 dishwaher F3 error
The eprom on these appliances is not reprogrammed by the use of what whirlpool call a SAM module. All this does is to reset the error code, and these sam modules have been a complete flop.
A very expensive piece of rubbish that a good engineer does not need.
In fact on two occasions the base module has packed in altogether when the fault code has been reset, and guess what Whirlpool Technical have no explanation as to why, the fault at the time was auto syphoning due to poor installation, reseting the module ###### it.
