If a F69 is displayed (circulation pump blocked)
With the circulation pump operating, the pump pressure level switch contacts are
checked. For this the heating relay must have been activated and both electronic unit
inputs must be potential free.
1. Check for proper operation of the heater relay, see
F25
Heating relay defective.
2. Check for proper operation of the heater pressure switch, see
F14
Water intake

3. Check the circulation pump for proper operation, see
F67
Circulation pump
speed too low.
If a F70 is displayed (Float switch fault)
The drain pump continues to operate do to the changeover contact of the float switch
B8/3 closed from 1 to 4 (refer to the wiring diagram). Even after the appliance has
been switched off, the drain pump can only be deactivated by disconnecting the
appliance from the power source.
1. Disconnect the appliance from the power source and remove the water from the
drip pan.
2. If there is no water, check for debris beneath the float switch Styrofoam.
3. Check the drip pan for any warps or dents that may have occurred due to
transport. Bend straight or replace as necessary.
4. Operate the appliance and check the unit for any oversudzing. Also check all
hoses, connections and threaded unions for leaks.
5. Check the float switch for continuity and correct operation. Replace float switch if
necessary.
6. Carefully dry all electrical components in the drip pan area.
If a F84 is displayed (Slide shutter positioning fault)
The electronic board is unable to read the position of the slide shutter through the
position switch. This fault is displayed when attempts to position the slide shutter
have failed. See
F63 (Slide shutter fault)
for troubleshooting steps.
If a F85 is displayed (Slide shutter signal change fault)
Even though the slide shutter has not been activated, a signal change has been
detected at the position switch.
Case 1:
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. The fault will be
indicated in the display or via LEDs. The buzzer is activated for 2
min.
