5. Troubleshooting
5.1 No water is delivered.
- Check the water pump fuse.
- Turn the delivery knob clockwise.
- Clean the filter in the water tank.
- Fill the clean water tank.
- Check feed pipes for kinks.
- Lock the plug at the red emergency lever
- Check operation of the pump.
5.2
The vacuum motor does not start.
- Check the automatic vacuum motor switch.
- Clean the dirty water tank around the sensor electrodes and the electrodes themselves.
- Do not move the electrodes from their original position; make sure they are not out of position.
- If the distance between them, or between the electrodes and the side of the tank, is modified, the power
cut-off mechanism may be activated by mistake.
- Observe how much foam is generated by the detergent used.
- Use Gansow´s low foam detergent.
5.3
Water is not sucked up, although the vacuum motor is operating.
- Make sure the drain hoses are closed.
- Check the tank lid is properly in place and lying flat on the water tank.
- Check the state of the tank gasket. Replace if necessary.
- Check on the state of the squeegee blades (see also points 5.4 and 5.5)
- Check that the suction tubes leading from the squeegee to the dirty water tank and the connectors inside the
dirty water tank are not blocked.
5.4 The squeegee with suction is leaving smears.
- Clean the rear squeegee blade.
- Check the rear squeegee blade and if necessary turn or replace. The rear squeegee blade may be used four
times.
- See also 5.8.
- Use the wheels to adjust the height of the squeegee from the ground.
5.5
The squeegee is stuck to the floor.
- Check the state of the front squeegee blade, in particular, that the slits are not blocked. If necessary, cut 1 to
3 additional slits.
- If excessively worn, turn the squeegee blades or replace them. The front squeegee blade may be used four
times.
5.6
The brush motors switch off.
- Check the automatic switches (thermal circuit breakers).
- Lock the plug at the red emergency lever
- Batteries are flat, charge immediately (red LED of the BEM is on).
5.7
The dirty water does not drain out through the hose.
- Remove any blockages from around the drain hose coupling in the dirty water tank.
- Remove any blockages in the drain hose itself.
5.8 The machine is leaving a smeary film behind it (the flow of liquid to the brush has either been cut off or
greatly reduced).
- Turn the delivery knob clockwise. (See also 5.1)
- Clean the filters in the clean water tank.
- The clean water tank is empty. Fill it.
- See also 5.1.
