Question

We have a Morco Ecoplus 6L water heater in our mobile home, the problem with it is the water will not get hot now, it is lukewarm what could the problem be please

Answer

This is probably a problem with the diaphragm, In the Morco D61E, if it is weeping air or water passed the diaphragm it will stop the gas valve opening completely.

It would be worth checking to make sure the main regulator outside is giving the correct pressure as if it is not then this will affect the operation, the easiest way of doing this is to run every other gas appliance in the van flat out and make sure the flame pictures still look good and the flame height does not drop.

It could also be a problem with the gas valve or a dirty burner, this however would need to be looked at by a Competent person
