What is the G model number? (I sent you an email.)
If it is a gen 5:
3.37 Fault Code F85: Slide Shutter Signal Change Fault
Symptom:
Even though the slide shutter has not been activated, a signal change has
been detected at the position switch.
If the fault is registered before the circulation pump has been activated for the
first time (or before program start), the program is interrupted and the drain
pump is operated.
If the fault is registered later, the fault message will be indicated in the display
at the end of the program.
Cause:
Position switch B3/12 defective; intermittent contact.
Remedy:
1. Check for dirty contacts; clean or replace circulation pump as necessary.
2. Check for pulses during operation at ST14 on the electronic, using a
multimeter set for low-voltage DC. If there are pulses every 30 seconds,
then replace the electronic (Section 100-4.5 or 100-4.6). If there are no
pulses, replace the circulation pump (Section 050-4.13).
Cause:
Electronic defective.
Remedy:
Replace the electronic. See Section 100-4.5 or 100-4.6.
3.11 Fault Code F11: Drainage Fault
Symptom:
Water present in appliance and is not being drained off.
Background information:
After each drain pump step, the circulation pump operates for 2 seconds and
heater pressure switch B1/13 checks the water level. See Figure 080-6. If it is
too high (large quantity of residual water remaining in the cabinet), the
drainage time is extended. If, after a further check, the water level is still too
high, then the program is interrupted, the fault code is saved and the drain
pump is activated.
Figure 080-6: Circuit Test Path for F11
Fault code F11 is also registered if heater relay 1K1 is not activated after the
fault code F51 register check; see Section 080-3.27.
Cause:
Drain hose kinked.
Remedy:
Check the drain hose for correct positioning.
Cause:
Drain blocked.
Remedy:
Check for proper water flow from the drain line by performing the following
procedure:
1. Disconnect drain line from drain trap, garbage disposal, or drain pipe and
place in bucket or large container.
2. Ensure that adequate water is in the dishwasher cabinet. Select and start
a new wash program (first step should be a 30-second drain). Ensure that
the drain hose is held in place within the bucket or container.
3. If water flows from the drain hose, the dishwasher is not the cause of the
blockage. Blockage is in the piping and should be checked by a
specialist.
If water does not flow from the drain hose, then check the filters.
1. Clean the on-site drain.
2. Check the sump drain.
3. Check the filters for blockage.
4. Check the heater pressure switch and replace it, if necessary. See
Section 050-4.16.
Cause:
Ball in non-return valve in sump has not opened (e.g., jammed).
Remedy:
Check the non-return valve for blockage; clean or replace as necessary.
Clean the non-return valve in the sump or replace it if necessary.
Cause:
Drain pump defective.
Remedy:
With the non-return valve removed, check the drain pump for proper
operation by performing the following steps:
1. Check the drain pump impeller blades for proper rotation. If stuck, look for
foreign objects blocking impeller blades. If impeller blades are jammed
and no foreign objects are found, proceed to the next step.
2. Remove the lower service door panel.
3. Operate the dishwasher in a drain step.
4. Check for power at the drain pump. If pump is receiving power, then
replace the drain pump. If not, check wiring from electronic to the drain
pump. Replace or repair as necessary (Section 050-4.17).
Cause:
Foreign objects in heater pressure switch.
Remedy:
Check the heater pressure switch for blockages and correct switching point.
Ensure that the contacts are in the correct position after a drain step. Replace
if necessary. See Section 050-4.16.
Cause:
Heater relay defective.
Heater relay (coil or contacts) becomes defective during the drainage step
(after fault code F51 register check).
Remedy:
Replace the heater relay. See Section 050-4.10.
