The display unit for electrical use is showing red all the time even though I have checked and no high use items are on. The gas reading is ok. Is this a fault with the display unit or is there an electricity supply problem.
I have moved your question here as others have asked something similar. The best advice we can give is to do a test.
First, turn off all appliances and sockets etc to see if the light changes at all, if it stays on it could simply be an indicator that the IHD is communicating with your home network, which is a good thing.
If when you turn everything off, the light goes out. turn devices on one at a time to see if a particular one sets it off, or see if it is just showing red to indicate usage.
Let us know how you get on.
