Trouble Shooting
6 Replenishment
6.1 Replenishment pump does not work or works insufficiently
7 Dryer
7.1 Dryer fan does not run or runs with too low speed
• Check the correct connecting of the fan cables: bl = blue; bk = black; br =
brown .
• If the fan supply lines have been transposed, the dryer fan will run at half the
nominal output only.
8 Water
8.1 Rinsing water does not flow
• The water pressure in the water supply system is too low: Minimum pressure
2 bar (29 psi).
• The valve opens, but no water flows through: filter at inflow is blocked.
• Check the green water inlet hose inside the machine.
• The water level switch is not positioned correctly: switching point is too low
(below the overflow level), therefore no fresh water is supplied.
• The level switch is defective (e. g. permanently open).
• Start the unit in manual mode and measure the voltage at the connection X4.
If no voltage can be registered, replace the power output section PCB.
8.2 Water tank overflows
• Water drainage hose (overflow) should have a constant fall. The hose end
should be positioned above the drainage level in the syphon.›‹›‹
• Check water drain opening in the tank and the hose for blockage and resi-
dues.
• When extreme algae growth is noticed, the overflow can be connected
directly at the back of the water tank.
8.3 Rinsing water constantly switches on and off
• At regular intervals (approx. 1 minute on and 1 minute off): The water saving
mode has been activated.
• At short intervals: th level switch is not positioned correctly (exactly on the
overflow level). Insert the rack. If the error continues to occur, readjust the
height of the level switch.
• Check filter in the suction pipe (repl. container) and clean it if necessary.
• Replenishment hose aspirates air. Check connections.
• Check eccentric position. Flow rate is 240 ml/min at maximum eccenter posi-
tion 100%.
• (60 Hz: 240 ml/min at 85 %!)
• Measure the voltage at the connection X6 (replenishment pump) on the power
output section while the replenishment is switched on (in manual mode). If no
voltage can be registered - replace the power section PCB. Remark: 2 pump
version: developer replenishment pump at X6 and fixer replenishment pump
at X5.
• Clean valves inside connection tube of pump.
Install valve-insert correctly: Pay attention to flow-through di-
rection!
