Trouble Shooting
6 Replenishment
6.1 Replenishment pump does not pump sufficiently
6.2 Replenishment rates are too high or too low
• The replenishment rate can be changed by adjusting the stroke of the pump.
To do this, the eccentric on the replenishment pump must be adjusted. Maxi-
mum pump capacity is 240 ml/min.
6.3 Adjust replenishment pump
• For the adjustment of the eccentric first open the allan screw on the big
eccentric with the red line. If screw is not reachable, then start the replenish-
ment pump by turning the temperature knob to “Manual pumping” until the
allen screw is visible.
• Turn the eccentric so that the red line will be at the desired position and
tighten the allen screw.
7 Dryer
7.1 Dryer fan does not function or runs with reduced speed
• Check the fan wiring: bl = blue; bk = black; br = brown.
• If the fan is connected improperly, then the fan runs only half power.
8 Water
8.1 Rinsing water does not flow
• Water pressure in the water system is too low: Minimum pressure 2 bar (20
psi).
• Valve activates, no flow passage - filter at inflow is blocked.
• Check green water inlet hose inside the machine.
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 drainage in the tank and hose for dirt, algae, or blockage.
• When extreme algae growth is registered, the overflow can be connected
directly onto the fitting of the water tank.
• Check filter in the suction pipe (replenishment container) and clean it if neces-
sary.
• Replenishment pump sucks air in. Check hoses and connections.
• Check eccentric position. Capacity approx. 240 ml/min at setting 85%.
• Activate the “Manual pumping” and while on, check the voltage of connection
X2 on the power circuit board. If no voltage can be registered - exchange
power circuit board.
Minimum setting must not be below 60%.
• Clean valve inside connection tube.
Install valve insert correctly: Pay attention to flow-through di-
rection!
