Rectifying errors

The pump will not switch on or switches off automatically (status bar red).

The battery is empty or damaged.

Charge or replace the battery.

Pump or battery are overheated.

Allow the pump and battery to cool down before you switch the pump back on.

Check if the pump is being overloaded: The hose at the outlet (1) must be clear and passable, the suction head and delivery head must not be too high.

The impeller is jammed.

If necessary, clean the impeller (20) and the pump housing. If the impeller is faulty, replace it.

The motor has a fault.

Have the pump checked by a Bosch after-sales service centre.

Not enough water is being conveyed.

One of the hoses is blocked or damaged.

Check that both hoses are intact and freely passable. Remove any blockages or replace any damaged hoses.

Suction head or delivery head is too high.

Set the pump up so that the height difference between the pump, the water discharge point and the highest point of the outlet hose is as small as possible.

The hose is not suitable (e.g. diameter too small, hose fabric too unstable).

Use a sturdy hose with a diameter of at least 19 mm.

A hose connection is leaking.

Only use hoses with a G 3/4" thread.

Make sure that an undamaged and tightly fitting flat gasket is placed between the hose and the hose connection of the pump and that the hoses are correctly screwed on.

The impeller is worn.

Replace the impeller (20) and the sealing ring (21).

The cover of the pump housing is not tightly sealed.

Make sure that the sealing ring (21) is installed, undamaged and correctly fitted. Tighten the four screws on the cover (15) until hand-tight.
