SECTION 4 - FAULT FINDING

4.16 NO HW BUT CH ON

Does the display show “dH” when a tap is on?

YES

Are the flow rates correct as per Section 1.16.

Is the wiring between the PCB and the diverter

valve actuator connected?

YES

Check diverter head fully engaged onto

waterset body

YES

Is diverter stuck in the CH position

YES

Check and replace diverter valve actuator head.

Is Boiler DHW OK?

Change diverter valve assembly.

Adjust flow rates to achieve 35º

temp rise and check filter fitted in

turbine is not blocked with debris.

Reconnect wiring or

replace wiring harness if

no continuity.

Re-engage diverter

head.

Replace PCB

Is hot and cold pipework crossed?

Is the wiring connected

between PCB and DHW

sensor?

Remove the turbine, and

check for debris in the

turbine. Replace turbine

if necessary. Is DHW

OK?

YES

Re-connect wiring

Replace turbine sensor

4.17 NO DISPLAY

Is there 230Vac to the boiler at L and N?

Replace PCB

YES
