What it is

The Wilo RAIN1-45 EM is a pump used in the Wilo Rain1 appliance family, running on a single-phase 230 V, 50 Hz supply at a rated power of 0.8 kW. It provides the water movement duty within the Rain1 system as specified by the manufacturer. This listing covers the pump unit itself.

Signs this part needs replacing

  • The pump runs but delivers no water.
  • The motor hums without starting or turning.
  • Water weeps from the pump body or its connections.
  • Repeated overcurrent or RCD tripping when the pump is powered.
  • The motor runs hot or cuts out on thermal overload.

Before you order

  • Confirm the existing unit is a Wilo RAIN1-45 EM.
  • Check that the supply is single-phase 230 V, 50 Hz.
  • Confirm the 0.8 kW rating matches the failed pump.
  • Isolate the power and water supply before removal.
