PROBLEM 3 – TOO LOW WATER STREAM
The last, occasionally occurring failure is a low water stream. Apart from the obvious damage
to the pump (no reaction with the plugged-in power supply), a reason for such a state can be incor-
rectly set waterflow regulation toggle (1) (Fig. M), bent hose providing the water for wheel protection
(2) (Fig. N) or a dirty filtering sponge (3) (Fig. N). In order to eliminate this problem, make sure to set
the toggle in the maximum open position, and check if the water hose is not bent or cut.

In order to clean the sponge, remove the transparent casing (it can be slid with an upward movement
