A Worcester 230 combi under direct mains pressure feeds a kitchen mixer tap, and the same pipe run continues to a bathroom sink mixer tap [and bath/shower].
The kitchen tap, installed in June, is a Hansgrohe Focus E mixer tap which has a flow rate of 12 l/min. at 3 bar. All worked well until recently. Either tap when drawing hot water would cause the combi to come on, so long as the flow was above half way or so between the off and full on position.
When the flow was lower than this the combi did not ignite, or cut off, probably because of the flow sensor.
This week, with the central heating on, the kitchen tap will not ignite the boiler even when full on. The bathroom basin tap continues to fire up the 230 ok.
Turn off the [2 bedroom flat] central heating, and after a few minutes the kitchen tap will enable ignition again.
Unable to find a service manual online except for the 24CDi/28CDi/35CDii (are they similar ?) can someone confirm if the Worcester 230's flow sensor is adjustable ? Or is this likely to be another case of the infamous Worcester diverter valve playing up ?
