– Pump leaky
Note:
3 drops/minute are allowed.
With stronger leak, have device
checked by customer service.
Note:
Condensate can cause increased
drop generation on the appliance.
– Leak in the high pressure system
Check high pressure system and con-
nections for tightness.
Leave the appliance running with open
detergent dosing valve and closed wa-
ter supply, until the boiler is sucked
empty and the pressure falls to "0".
Open the water supply again.
If the pump still is not sucking in any deter-
gent, it could be because of the following
reasons:
– Filter in the detergent suck hose dirty
Clean filter.
– Backflow valve stuck
Remove the detergent hose and loosen
the backflow valve using a blunt object.
– System care bottle empty.
Replace the system care bottle.
– Water shortage
Check water supply, check connec-
tions.
– Heater defective.
