Fisher-Paykel DD603 F1 code

7 posts in this topic

This unit has a the upgraded link supports, lid actuators and mains board as of a year or so ago (thanks to this forum). Now I'm getting an F1 code on both drawers. So what are the next-level possible root causes?

If neither drawer or inlet valve is leaking and the base is dry, could be a shorted flood sensor on the mains filter board.

There is plenty of water, so the flood sensor is not giving a false reading. The water is under both the upper and lower drawer - so if the inlet valve is the one under the lower drawer, that is probably not it.

 

I'm perplexed because the link supports and lid actuators are recent upgrades, so I'm not sure what else could cause a leak. It doesn't appear that there was something in the tub keeping the lid from closing, though I guess that is not out of the question. How often do the lid seals themselves fail? What else I should check?

 

Should I replace the mains filter board as a precaution now that it has gotten soaked?

• Lid not closing.

• Overfilling.

• Foaming.

• Not draining.

• Lid seal damaged.

• Dispenser or water softener or their seals leaking.

• Damaged water inlet or drain hoses.

• Leaking heater plate or motor seals, or drain o-ring seals.

• Yoke jammed or broken.

• Inlet hose to inlet valve connection loose.

• Inlet valve body leak.

• Heater plate damage (chipped enamel).

• Dry F1 – PCB mains filter, harness or connectors, electronic controller.

 

Dry Mains filter with hair dryer, should be fine.

Concur with Brother Chat.  Upper drawer is the source of the leak and I have had to replace the lid assy to correct a leak, usually after replacing the actuators and installing the link retrofit kits.  Provided there's no water or soap traces on the bottom access cover, particularly near the drain hose connection, it could be the upper drawer lid (which comes with LH and RH yokes).

I think one of the fold down shelves on the side of the upper tub was out of its slot and up, and that was enough to hold the lid open a bit (not a very foolproof design).

 

If the problem occurs again I guess I will replace the upper lid assembly.

 

By the way, the flood sensor is really sensitive - the area under the mains filter board has to be DRY. I mopped up the water in the lower pan, of course. Then to actually get the F1 error to clear I removed the mains filter board cover, unscrewed the board, and lifted it out of position (without disconnecting anything). This allows enough play in the gray plastic mounting assembly that I was able to slide a paper towel underneath. Air drying for several hours is not enough by itself, and I'm not that thrilled about putting heat from a hair dry on those parts.

hair dryer will dry it all out

 

water will stick onto the mains filter board

 

water can also get into the wiring and can takes days to dry out
