Hello and what a great forum. I am troubleshooting my dishwasher for a problem with the top drawer. It will not run a load of dishes. I can start the cycle and hear the rotor turning at high speed, but after a couple of minutes, the screen will flash blue and there is a small symbol that looks like a faucet with a slash through it that is displayed. I also saw an F2 code displayed today for the first time.

I have cleaned all of the removable parts in the tub and inspected the rotor for any binding or damage and it all looks fine. I visually inspected the stator windings for evidence of overheating and it all looks good. I have a copy of the service manual and was able to enter into the Hardware Output Test Mode. I cycled through the different outputs in sequence and everything seemed to respond correctly, except for the motor output wash direction, P1. The motor output drain direction works just fine. I observe a scrub brush icon on the display that switches on and off as I toggle the various outputs. However, the brush never appears when I attempt to run the P1 function. Any ideas?

will the unit fill with water?

Faucet with a slash through it usually indicates

there's no water getting to the unit.

You wanna be sure that you have water in your machine before you go energizing the heater too long in diagnostic as it has an internal fuse that can open without the water in it to dissipate heat - How's the bottom drawer working ?

I thought that icon indicated no water flow; however, when I cycle through the hardware outputs, I can fill the tub with water, function FU. I assume that means the fill valve is responding correctly to the controller in automatic as well as manual.

Thanks for the warning about the fuse - I will keep that in mind. Where is the heater element physically located? Is the Er function for element relay what toggles the heater on and off?

The bottom drawer is working just fine.

Thanks for the diagram!

Welp, I suppose I'd better swap controllers and see if the problem follows it or stays with the top drawer.

Fill level - successful fill is sensed by the load on the pump ... so if the pump isn't running in the recirculate direction, there is no load to sense and a fill error may occur. However, if the rotor/impeller isn't rotating, an F2 error should trigger as well ... unless perhaps the rotor is spinning but the impeller is broken or loose from the shaft.
