The float cables inside the tank were rotten. The wire snaps inside the insulation when the cables are stripped back. Two floats, the assist float and the high-level float, were not working because of water getting in. The junction box inside the tank was full of water.

The junction box was replaced and the chamber was working in automatic.

- Repair: the junction box was replaced.
- Result: the chamber was working in automatic.
- Still outstanding: the chamber ran off one float, with no high-level float working.
