Pulsacoil 2000 T1 sensor
Hi
I had not hot water (just tepid) and flashing led light suggested I had both sensors faulty. I've just manage to change both PHE return sensor and the DHW temperature sensor. Unfortunately once I turned on the boiler the led light blinks 7 times pause and 7 times again (if I hear carefully there is also a mild buzzing noise) suggesting the T1 is faulty. I ask myself what are the odds!? . I notice that there is not current running through any of the Rod Thermostats, is this because the DHW senso appear to be faulty "again"?
What would you suggest to do next?..
Thanks for helping

The rod stats are not controlled by the DHW or PHE sensors.
Is the a relay on your unit?
Also check the sensors are wired correctly.

Check the following also
The sensors are connected to the PCB, check they have been wired correctly and you are receiving voltage to your pump. Also check your overheat stat has not tripped which will prevent electricity reaching your thermostat rods.
