Only cold water coming from Grohtherm wireless 36023


There are multiple possibilities:
- the power to the main control could be off (seems unlikely if you can turn the water flow on and off)
- the thermal element that heats the water could be burned out (may not be a problem if this is only a mixer unit and relies on external hot water supply)
- there could be a problem with the solenoid that opens to allow hot water to flow through the unit
- there could be either no hot water getting to the unit or blockage so that hot water will not flow through to the mixer

Start by making sure there is power. Then you may need to disconnect the hot water supply (after turning it off at the source) and then check to see that hot water will flow. If you get hot water to the unit then there is something internal keeping the hot water from mixing with the cold.

I have a Potterton Combi Puma 80e When I use the shower the pressure seems to drop and shower goes cold! except when the central heating is on shower works fine


Does the red status led in the centre of the control board come on when hot water is drawn? You need to remove ONLY the front decorative cover to see the control board, two fixing screws at the base of it. If not the boiler won't fire when the CH is off.
The trigger for this is a pressure switch, replacement of which is beyond DIY scope.

My shower is run off a combi boiler and recently started to go cold for a couple of seconds every few minutes and nobody is running water elsware in the house.


Check the hot water flow at the shower - if it's as good as other taps the boiler diverter valve is suspect. Replace either the complete valve or the internal rubber diaphragm, depending on the boiler make

Shower goes hot and cold


If you are having trouble only at the one fixture (shower), and no where else, the problem is most likely in the shower valve...which either needs new cartridges, or a complete replacement.
hope this helps

Installing a Mixer Shower from a Combi Boiler.


hi there, your boiler will perfectly match the mira excel ( a great choice i might add) a 24cdi will give about 9.8 litres a minute flow rate hot water.
The mira excel is suitable for any plumbing set up and there installation instruction are very well laid out & their helpline is fantastic.
The hot water will fluctuate accordingly to the time of year as the cold water temp coming into the property will vary. but the boiler will modulate to compensate.So in brief in the summer you will notice it hotter than you would in the winter, this has nothing to do with the boiler just the incoming temp of the cold water.
