• 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 eccentric position 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
7.7
Dryer
7.7.1 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
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)
• 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
7.8.2 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 residues
• When extreme algae growth is noticed, the overflow can be connected directly at the back of
the water tank
7.8.3 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: The 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
