7.7.3
Dryer ventilation is too weak
If the ventilation is connected incorrectly, it runs very slowly (heating element in the air channel starts
to glow).
Dryer ventilation connection:
7.7.4
Dryer temperature cannot be reached
• Check temperature sensor: Measure voltage at X24 on the power PCB between pin 3 (green)
and pin 2 (brown). The value should read 0.32 V at a temperature of 32 °C.
• Only cold air flows from air channel: Heating element in air channel is defective. Disconnect
X12 clip on the power PCB and measure resistance of heating element (approx. 26Ω).
•
Enter dryer temperature of 70 °C. Check voltage of X12 on power PCB. If no voltage can be
registered exchange control unit.
7.7.5
Dryer temperature display exceeds the set value
• Check temperature sensor: Measure voltage at X24 on the power PCB between pin 3 (green)
and pin 2 (brown). The value should read 0.32 V at a temperature of 32 °C.
•
Enter dryer temperature of 35 °C. Check voltage of X12 on power PCB. If no voltage can be
registered exchange control unit.
7.7.6 Dryer temperature cannot be reached or is too high (display shows values approx. 30 °C
and 75 °C)
• Check temperature sensor. Sensor is either not connected or defective.
7.8 Water
7.8.1 Rinsing water does not flow
• The water pressure in the water supply system is too low: Minimum pressure 2 bar (29 psi)
•
Valve activates, no flow passage - filter at inflow is blocked.
• Check solenoid valve.
7.8.2 Water tank overflows
• Water drain hose (overflow) should have a constant fall. The hose end should be positioned
above the drainage level in the syphon
• Check water drain line to the tank, hose and connection for residues
• When extreme algae growth is noticed, the overflow can be connected directly at the back of
the water tank
