BIASI RIVA COMPACT HE M96.28SR/C BOILER

[PJSK]

Hi,

I had a BIASI RIVA COMPACT HE M96.28SR/C boiler fitted about 3 years ago by a Corgi registered boiler engineer, every radiator was also replaced as was most pipe work. The hot water started to run hot and then cold for at about 20 second intervals and we can no longer use our shower or bath, I have replaced the DHW/HE as this seemed blocked with black debris, I have also replaced the microswitch and small membrane but the plunger does not come out when the hot water is turned on so I have had to put a nail in the microswitch for the time being. Have you any idea why the hot water is running HOT/COLD/HOT and the plunger is not working?

I am very reluctant to help anyone who blatently bypasses a safety device like that.

Did you check the pump impeller to see if its blocked.

The main heat exchanger of the boiler may well be blocked or some of the waterways associated with the flow switch.

What does the installer have to say? Evidently he did not power flush the system when he installed your boiler.

Hi Tony, the installers (GORGI Registered) have gone out of business and moved up north!, the BIASI engineer put the nail in the micro switch not me and he has gone home to Portugal, the second BIASI engineer that I had to call out said the problem could be anything and could not resolve it, he said leave the nail in?. I am an accountant and not a plumber but the impeller is not blocked and the new DHW/HE now also has black bits in it?. That's why I think the best solution is to get another boiler installed and the system flushed first.

no need to fork out for a new boiler

contact Gas SafeRegister and inform them of the shoddy and dangerous work done by an alleged GSR engineer (biasi chaps),and ask for an inspection.

contact biasi and let them know you have contacted GSR. biasi have either been called out on a warranty repair or a fixed price repair.

either way biasi have not repaired anything!!

biasi will ask to resolve the matter,tell em you want a flush and new boiler with 5 year warranty and servicing.

or 2 of their boys are going down

Your boiler is potentially fine and any boiler would suffer from similar problems if fitted to a dirty syste,

Glasgowgas doesn't seem to understand how Biasi and many other boiler firms deal with warranty calls. Your call was presumably outside the warranty period.

Biasi have a large network of service agents who do their warranty calls. Out of warranty calls are dealt with by the same engineers but thats a private arrangement between you and the engineer. Nevertheless Biasi are concerned that their service agents are giving a good professional service and you could call and complain tomorrow morning.

A new boiler will cost you about £800-£1000 including a powerflush. A power flush and dealing with the boiler will cost about £400 ! As an accountant you should be able to see which option is better value.

Its your original installer who was at fault not cleaning the system.

agile you also stated in your first reply " i am very reluctant to help anyone who blatently bypasses a a safety device like that"

the OP then tells you HE did not bypass safety device, Biasi did.
wether Biasi subbed thr job to another firm is irrelevant, wether it was a warranty call or wether the OP paid for Biasi to come out and carry out a repair is all that is relevant.

the job has not been done,a shoddy piece of bypassing a safety device has been put in place as a stopgap

and you have the audacity to come back on this forum and state that the boiler is now potentially fine!

why contact Biasi and let them know that their engineer ( or a representative of Biasi) has bypassed a safety device.
your advice should be to contact gas safe register immediately and report this shoddy and potentially dangerous work

but the OP states he did change these parts and then promptly changes his post when challanged by Agile, sounds like a DIY fixer who does not understand what the hell his doing.

Again you are not differentiating between the Manufacturers and an engineer who sometimes does warranty work on behalf of Biasi.

In this case, according to the OP, the job was out of the warrantee time ( and would not be covered by the warrantee anyway ).

In this case the decision was taken to allegedly bypass the flow switch. That was nothing to do with the boiler manufacturers, we are just told that it was the engineer's decision.

I have seen many of these situations described and my advice is that there is often more than one story of what actually happened.

[glasgowgas]

tony, you have totally lost me on this thread.

you were down the OPs throat in your first post.

your second post, you are trying to get at me, then tout for work with a sweeping quote to supply/fit/powerflush boiler

your third post states that i still cant tell difference between warranty calls and engineers who sometimes do warranty work on behalf of Biasi.

the OP has not come back on so you are making a lot of assumptions,but what we do know is the OP has stated that on two occasions a Biasi engineer has been out,first one stuck in a nail,second one could not resolve it.

i stand by my posts, report biasi( or their representatives who made shoddy and unsafe repairs) to gas safe.
ps, nice touch on other posts regarding removing pump heads for cleaning
before telling them its a blocked heat exchanger

imatation is the lowest form of flattery

The pin doesnt come up because theres that much crap behind it or perhaps the diaphragm is knackered.
If theres that much crud behind it then the pump will have been hammered by the dirty system as well so that may be on its way out and not strong enough to push the pin up onto the m/switch.
The same crud will have put a nice coating on the thermistor which will now give the wrong resistance to a current sent by the pcb to modulate the gas valve resulting in hot and cold water.

As it happens I had one nearly the same a couple of weeks ago. In this case the diaphragm was fine but the pump was hammered. The trade price of the new pump head alone was about 4 times what a Wilo pump costs in B&Q

Just lately I have really noticed that many are now starting to pay the price for getting the cheapest installers. [You can often tell they haven't paid much for the installer by what they pay for the boiler.]
I'm getting more and more work powerflushing and fitting magnacleans than ever before.

Thank you both for your comments, I am still none the wiser and my boiler still does not function correctly, still running hot/cold/hot/cold water, I will call Biasi again.

 

[Agile]

Running hot-cold is a classic symptom of a blocked plate heat exchanger. Thats only to be expected when your system is very dirty.

There is no point in calling Biasi if its out of the warrantee. Even if it was within the first year it would not be covered anyway because its the installers "error" in not cleaning the system!

Better to call your solicitor to take your installer to court for not power flushing yor system, when he fitted your boiler.

In the meantime you need a competent engineer who can clean out the boiler and get it working again. Those problems will then reoccur if the system is not flushed out.

This is typical of a poorly installed boiler but more common when the installer was not CORGI registered.

Thanks Tony

That flow switch is a safety device and should not have been by-passed. I would classify your boiler as 'At Risk' if it is still in a by-passed state.
