Troubleshooting:
Cleaning performance with the cleaning attachment is insufficient:
• The rotation nozzle is not turning
• Scaly deposits on the rotor
• Blocked by particles of dirt
• Turn multiple time manually (make sure the high pressure cleaner is depressurized before doing so)
• Disassemble and clean
• In case of excessive and sudden water pressure, the cleaning head can freeze. In this case, press the high pressure
cut off trigger multiple times.
• Is the high pressure cleaner producing sufficient pressure?
• Is there a sufficient supply of water to the high pressure cleaner? (Inlet line must be ¾")
• The rotating nozzle may be worn and need replacing.
• No water is being discharged from the suction unit:
• Air pocket in the pump
• Is the power lead for the immersion pump plugged in at the suction basket?
• The immersion pump is standing in mud and can't extract water
• Discharge hose kinked.
• No vacuum or insufficient vacuum:
• Vacuum flow interrupted due to excessive solid build up in filter basket
• Machine switched off by thermocouple (caused by vacuum flow interruption / blocked, kinked, or sagging suction
hose / excessive water temperature)
• Is the top section with motor positioned precisely on the lower barrel?
• Check the sealing ring on the filter basket between the barrel parts for signs of damage and soiling
• Check the suction hose coupling
• Only one suction motor switched on
• Rollers on the cleaning attachment not turning:
• Casters stuck or dirty. Move attachment back and forth on a durable, insensitive base by applying a slight pressure.
Replace the casters if they cannot be freed.
• Water escaping from the attachment:
• Clean sealing brushes to remove clogging, or replace brushes.
• Insufficient vacuum build up
• Incorrect height setting of sealing brushes
• Vacuum flow interruption triggered (clean filter basket)
• Unable to actuate cleaning attachment trigger:
• Release the lock
• Vacuum switching off:
• Machine switched off by thermocouple (caused by vacuum flow interruption
• blocked, kinked, or sagging suction hose / excessive water temperature)
• Check power supply: the circuit breaker may have triggered. Use only 2.5mm² diameter
• extension lead. Total length must not exceed 30 metes. Completely unwind extension reels.
• Bellow air filter below suction unit wet and / or soiled
• Check if the pump plug is plugged into the suction unit (otherwise the water level will rise and the vacuum flow
interrupter will trigger).
• Switch motors on individually.
• Attach all machines to different power supplies.
• Check the 230V power supply.
• Set both main switches to "0" position. Remove the cause of the malfunction and switch the machine back on after
waiting for approx. 5 min.
