What it is
The Hamworthy 533901035 is a time delay relay rated at 220/240V AC, used to control pump over-run on Hamworthy Warmwell HE fully automatic floor standing boilers. It keeps the circulating pump running for a set period after the burner shuts down, allowing residual heat to be dissipated from the heat exchanger.
Signs this part needs replacing
- Pump stops immediately when the burner shuts down, with no over-run period.
- Boiler overheating or tripping on the overheat thermostat after a heating cycle.
- Residual heat not cleared from the heat exchanger, causing noise or kettling on shutdown.
- Relay contacts pitted, burnt or showing signs of arcing.
- Intermittent or absent pump over-run.
Before you order
- Confirm the boiler model against the fit list above.
- Check the existing relay's voltage rating and terminal arrangement match 220/240V AC.
- Isolate the electrical supply before removing or testing the relay.
