The Dryer Ventilation Is Too Weak; The Dryer Temperature Cannot Be Reached; The Dryer Temperature Display Exceeds The Set Value; Dryer Temperature Cannot Be Reached Or Is Too High (Display Shows Values Approximately 30 °C And 75 °C) - Kodak 212 Service Manual

Troubleshooting

7.3 The dryer ventilation is too weak

• If the ventilation is connected incorrectly, it runs very slowly (the heating element in the air channel starts to glow).
Dryer ventilation connection:
X9 L black
X9 Z brown
X10 N blue
X10 PE yellow / green

7.4 The dryer temperature cannot be reached

• Check the temperature sensor: Measure the 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 the air channel: The heating element in the air channel is defective. Disconnect the X12 clip
on the power PCB and measure the resistance of the heating element (approximately 26 Ω).
• Enter a dryer temperature of 70 °C. Check the voltage of X12 on the power PCB. If no voltage can be registered,
replace the control unit.
• Verify the input voltage of 220 - 240 VAC with the heater actuated.

7.5 The dryer temperature display exceeds the set value

• Check the temperature sensor: Measure the 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 a dryer temperature of 35 °C. Check the voltage of X12 on the power PCB. If no voltage can be registered,
replace the control unit.
7.6 Dryer temperature cannot be reached or is too high (display shows values approximately 30 °C and 75 °C)
• Check the temperature sensor. The sensor is either not connected or is defective.

Water

8.1 Rinsing water does not flow, ventilation runs

• The water pressure in the water system is too low: The minimum pressure is 2 bar (29 psi).
• The valve activates, but there is no flow passage: The filter at the inflow is blocked.
• Check the solenoid valve.

8.2 Water tank overflows

• The water drainage hose (overflow) should have a constant fall. The hose end should be positioned above the
drainage level in the syphon.
• Check the water drainage in the tank and hose for blockage and contamination.
• When extreme algae growth is noticed, the overflow can be connected directly at the back of the water tank.
