There are foreign objects in the

pump.

See

Replace the pump.

7.3 Excessive ambient temperature

In order to protect the electronics from temperatures that are dangerously high,
the electronic control system monitors its own temperature.

• If the temperature is too high, the pump speed is automatically reduced.
• If the temperature rises above safety limit, the pump will shut itself off.
• The pump will automatically restart after cooling down.
