Before proceeding, disconnect the high pressure washer from the mains power supply via the disconnect switch or
by unplugging the cable from the power socket, and turn off the water supply.
PROBLEM
When the switch is turned, the high
pressure washer does not start.
No water jet is produced or there is a
leak from the high pressure water cir-
cuit; after 3 minutes the high pressure
washer shuts down and indicator light
"E" flashes.
The pump functions but does not reach
the rated pressure.
With the lance open, the pressure rises
and falls. After 10 pulses, the high pres-
sure washer shuts down and indicator
light "E" flashes.
In bypass or total stop mode, the high
pressure washer shuts down and indi-
cator light "E" flashes.
Following a total stop, the high pressure
washer fails to start and indicator light
"C and E" flashes.
Setting the temperature adjustment to
the desired position, the burner fails
to ignite.
Indicator light "D" comes on.
Indicator light "E" comes on.
Water not hot enough.
Indicator light "F" flashes.
N.B. To reset the fault signals, turn main switch "A" to pos."0" and then back to pos. "I".
During maintenance and/or repairs, use original spare parts only as these guarantee greater quality, reliable and
safety characteristics. Failure to use original spare parts absolves the manufacturer of all liability.
