My boiler seems to spend more time displaying the code S.53 than it spends heating up water. The result is that many of the rads in my house cool down before they get the chance to get properly warm.
Manual says: S.53 means Appliance is within the waiting period of the operation block function due to water shortage (VL-RL spread too big)
Please can anyone please shed any light on this (I am cold! )
