What does Block code S16 / Soft Starter block / block SS mean displayed on my heat pump (WPM / Touch screen based).

Block code S16 / Soft Starter block / block SS means the compressor is not running right now as the Soft Starter is blocking the heat pump from running. The Soft Starter is a device for starting a compressor and occasionally it will block the heat pump from running if the soft starter is not in a state where it can run. The supply voltage may have briefly gone out of specification, or the compressor had recently tried to start recently so needs more time before it can re-start.

If after 30 minutes the message is still on screen, power off the heat pump completely at the mains for at least 10 minutes, then switch back on again.

If the same message re-appears when the heat pump tries to start again, it may need an engineer to visit to check the soft starter and operation of the heat pump.
