until mixture has cooled down, empty the tank and remove them.
The beater’s motor is damaged. Call Assistance Service.

Inside break down. Call the Assistance Service.
ALARM CODE
The Display shows an alarm code P – – / PEE
TAKE THE POWER SUPPLY OFF at once by the Main Breaker.
Note:
Alarm signals are unusual but possible under special circumstances. Before deciding that machine is out
of order, switch machine off for as long as it takes to normalize temperatures (30...60 minutes), turn back
on and check for alarm signals.
Alarm code “P – –”: the TANK's temperature probe detects a temperature HIGHER than the safety limits.
Note: If a very high TEMPERATURE is programmed (see par. 6.3, P1 programming) the alarm may go
ff (this occurs, however, only in certain circumstances). Cause: Machi

Cause: The tank temperature probe is broken (interrupted or out of tolerance range). Call Assistance Service.

Cause:
The tank temperature probe is broken (due to a short circuit) or wiring is damaged. Call Assistance
Service.

Cause:
The tank temperature probe is broken (cut off or out of range). Call Assistance Service.
