Troubleshooting
Probe fails to operate
Perform the following diagnostic checks if the probe fails to operate as required:
1. Check that the water level in the boiler is at or above the level of the probe.
2. Recheck all wiring to ensure proper connections as specified in the wiring diagrams of
the boiler manufacturer or in this instruction manual.
3. Check to ensure that PTFE tape has not been used on the threaded connection of the
electrode to the boiler.
4. Some foaming is common in certain boilers. Refer to recommendations from the
boiler manufacturer for cleaning the boiler and piping when excessive foaming
occurs.
