The Ever- So- Helpful Diagnostics Mode -----
Getting into the Diagnostics Mode:
Press the LOCK and START / PAUSE buttons simultaneously and hold for 5 seconds.
The unit will beep once
Press the POWER button once, and you are now in diagnostics mode.
Pressing the START / PAUSE button sequentially advances the
machine through the various functions you will want to test.
Start and stop each function by pressing the LOCK button.
A strong word or caution: DO NOT ENERGISE THE HEATER PLATE
function (ER) without water in the tub or the heater will burn out.
The tech sheet containing all fault codes, test values, and a
schematic is located behind the lower drawer at the back wall.
Exit diagnostics by pressing power off.
Q: F1 ERROR. The unit is beeping, both drawers are flashing F1 and won't stop running.
A: Your appliance has experienced the ubiquitous F1
flood error. The only way to stop the beeping is to remove power. Your
course of action depends on the next step. You need to look BEHIND the
lower unit drawer. Remove power, then open the lower drawer all the way,
and press those plastic tabs (down at the sides, along the bottom and
just below the round buttons)- inwards. Now slide the drawer out a
couple inches more. You can now see behind the drawer.
Is there water in the catch pan? If no, the Mains Filter
Board beneath that plastic cover in the back is bad. It thinks it's
flooded while in fact it is not. Replace it. (PN 525959P) It is also
remotely possible that one of the wiring harness is faulty.
If there IS water back there, you need to find where
it's coming from. Usually, the fill (PN 526836) and drain hoses (PN
527137) are NOT at fault. Go into Diagnostics Mode, and operate the
water fill valve (FV), and look for leaks at the valve and along the
fill hose as the tub fills.
(You'll want to remove that large plastic cover in the
back to see the valves and hoses coming from them. Lift the drawer off
its rails and set it off to the left if there's space for it. Upper
drawer, set it on top of the bottom drawer).
Operate the drain pump (P2) and look for leaks in the
drain line. If no water is seen leaking from those sources, go on to the
Lid Motors and the Link Supports.
First inspect the link support (that white plastic rod
that spans the tub service lines). They typically snap in two at the mid
span point. If it's snapped, there's your problem. Replace it with the
updated link support. (PN 528437) Also run the Lid Motors (LD). As they
transition up and down, do they respond strongly, or do they sound weak
and labored? If the motors are in a white plastic case, you have the old
motors and they will need replacing soon anyway. When they grow weak
their ability to pull the seal down strongly is diminished (PN's 528112
Top, and 528113 Bottom)
Should you get an F1 error code on the TOP UNIT ONLY, it
means that the LOWER UNIT has experienced some failure in the Water
Heating Circuit. You will need to test those components to detect what
has failed. Get out the trusty schematic and your multimeter!
