Question about Air Conditioners

Open Question

I have Sime Format Boiler ("30E" model) for central heating only. Suddenly it stopped working. So I grabbed its manual and followed all start up instructions but - no result! No even green indicator light (power is ON). Any suggestions?

Since you have done a good job bleeding the system, I will suggest that the impeller on the pump is bad. Many times these will simply deteriorate in the volute causing the symptoms that you describe.

Go online to www.cheapboilers.com who deal with this type of boiler. It would be very difficult to troubleshoot this boiler with the information supplied. I hope this will be of some help to you.

They should also be able to get you a manual for your thermostat.

Hi,
It would be helpful to us if you had includes the make and model of the boiler that you are talking about...

Is it gas or fuel oil???

My impression from what you have said is that the control know as the triple aqua stat relay is bad and it is not tripping on the burner on a call for heat...or the circ. pump for that matter...but I have no idea if you have on of those on your unit or what controls you may have so I'm making a very fuzzy guess there...

At any rate your problem is a control issue and whatever controls your boiler needs to be repaired and/or replaced...

Problem with heating on ferroli optimax 31c


d2 is the code symbol for delay after central heating. and is not a fault code.. however if this is coming on then stopping the operation of the boiler then it usually points to a sticking diverter valve.

Bosch greenstar 30 CDi - no central heating or hot water!


it sounds like the system was not cleaned properly when the new boiler was fitted. all new boilers need to have the pipework flushed to remove any debris scale sludge and flux from the system. this is now usually done by a power flush which is basically a big pump mounted on a big bucket and it washes the dirt out of the pipework and collects in the bucket. if this is not done the dirt will block up the small passages in the heat exchanger. i suggest the system is cleaned flush and the heat exchanger changed to help protect the boiler a filter should be fitted (for example a magna clean) if the company who installed the boiler is corgi registered then they are liable for the damages. call corgi for advice.
