Sensor or pump?

Sensor or pump? Empty Sensor or pump?

Pulsacoil III.

The LED on the pump control board intermittently flashes quickly.

Drawing water works, and hot water for bath etc can be obtained.

After drawing some water, the LED changes to a slow flash, then intermitently goes back to rapid flashing.

Initially when drawing water the pump does not appear to work (while rapid flashing), once the pump is running this seems to 'remove' the fault.

Is this likely to be the sensor or the pump itself?

Hi Sneezy24,

This is classic sensor error. They do it intermettently as you describe sometimes. Definitely not the pump. Replace the sensor and all should return to normal.

(I take it your Pulsacoil III is the single sensor version. If yours has two sensors then replace the DHW (upper) one first.)

Cheers, Mike
