E008 on an Advantix S.p.A heat pump: Forced compressor shutdown for luck of lubrication
Short answer
On an Advantix S.p.A heat pump, E008 means: Forced compressor shutdown for luck of lubrication. The heat pump stops until the fault clears or is reset. An engineer is needed to fix the cause. The wording differs by model range — each is shown below.

On the MAXA i-290 (Gamma i-290)
The manual says: Forced compressor shutdown for luck of lubrication.
Part involved: compressor / refrigerant circuit.
When it shows: Compressor fails to reach ramp speed within 30 min.
On the MAXA i-32V5
The manual says: Compressor driver limitation alarm.
Part involved: compressor inverter drive board.
When it shows: Compressor fails to reach ramp speed within 30 min.
On the MAXA i-32V5 MIDI (i-32V5H Midi)
The manual says: Compressor driver limitation alarm.
Part involved: compressor inverter drive board.
When it shows: Compressor fails to reach ramp speed within 30 min.
On the MAXA i-HPV5H
The manual says: Compressor driver limitation alarm.
Part involved: compressor inverter drive board.

Is it safe?
| Does the heat pump stop? | Yes |
|---|---|
| Severity | Fault — clears by itself when the condition goes |
| Engineer needed? | Yes |
The heat pump stops until the fault clears or is reset.
Resetting itself: unknown.
Manual reset: manual after 3 trips per hour.
What you can check
- Note the code shown on the controller and the model number on the unit's rating label before contacting your installer.
- Check that the heat pump's isolator and consumer-unit breaker are on; do not open any casing.
What the engineer will check
On the MAXA i-290 (Gamma i-290)
- Record high/low pressures, discharge/suction temperatures and EEV steps with the unit running.
- Check water-side flow and air-side coil (blocked/frosted fins).
- Check pressure switches/transducers and wiring.
- Leak-test the refrigerant circuit and correct the charge (F-gas / flammable-refrigerant competent engineer only).
Who to ask for: Heat pump engineer.
Certification: Heat pump installer competence; F-gas and flammable-refrigerant (R32/R290) handling competence for any refrigerant-circuit work.
On the MAXA i-32V5
- Check supply voltage and phase at the unit terminals.
- Check compressor U/V/W connections and compressor winding resistance.
- Check drive board heatsink cooling and fan.
- Replace the inverter/driver board if faults persist.
