Cause
1. No supply voltage.

3. Outside temperature is too
low.
4. Motor is overheated.

condensation water (9)
leaks.
1. The hose connections have
a leak.

the pressure regulator (3).
Solution
1. Check the supply voltage,
the power plug and the

down. If necessary, remedy
the cause of the overheating.

any damaged seals replaced
by a service center.
