Level probe

Reseal the level probe

The most reported fault on this machine: the large nut at the level probe loosens and lets steam out. This follows a retailer's guide and owner reports. Several owners cured it by nipping the nut a quarter turn.

1. Unplug, let it go cold and take the top panel off.
2. Pull the blue connector off the probe.
3. Unscrew the probe by its large nut, a 19 mm hex. A deep socket is easier than a spanner.
4. Clean the threads and wrap them with 3 to 7 turns of PTFE tape.
5. Refit it without overtightening and push the connector back on.
6. Reheat with the steam wand open to purge the air, and check for leaks before closing up.

Clean the probe if the boiler overfills

If the pump runs on after a refill, the steam is wet and surging, or alarm 03 shows, the probe is not sensing the water. Owners list the causes in this order: a scaled or dirty rod, a rod sitting too high in its clamp nut, a loose connector, and rarely the control box.

1. Unplug, let it go cold and take the top panel off.
2. Take the probe out and clean the rod until it is bright.
3. Push it back to its depth and nip the small nut.
4. Check the connector at the probe and at the control box.

Owners' test: pull the wire off the probe and touch it to the boiler body. The pump should stop. If it does, the wiring and control box are fine.
