8.8. Heater Element Removal
1. Remove Tank Lid sub-assembly as per section 8.6
2. Undo the two 18mm lock nuts and slide the heater element tabs through the holes in the lid.
8.9 Thermistor & Level Probes - Cleaning & replacement
There are 3 probes (low level, high level and overflow) on the Mix Boiler range.
Each probe is ‘push-fit’ mounted into a silicone mounting grommet.
The low level and thermistor are paired together in one grommet and the high level and overflow
level probes are paired together in the other.
The Tank lid sub-assembly does not need to be removed to access the level probes as they can be
pulled from the silicone mounting grommet by the metal electrical tab – the descale funnel can be
pushed gently out of the way to access.
