Serious Noise from Boliermate System

Post  royb on Fri Jan 23, 2015 2:53 am

I have a Boilermate OV Model 4200 in my house and last night twice there was a loud noise like a plane landing. It hasn't happened since. I isolated the noise to the Boilermate. The overflow tank is at about 50 degC. I wonder if it could be a blockage in the system that has cleared itself.
Does anybody know how to interpret the S1 and S2 codes on the fromt of the Boilermate.

Could be there is sludge etc.
And the system "vented" into the F & E tank.
Read the book or look inside the lid / cover.
Go through the codes step by step.
And read the manual all will make sense then.

Thanks, I will look in the tank.
The book I got with the boiler is not very detailed and doesn't detail what the codes mean, just how to get them by depressing S1 and S2. Can I download a detailed manual from the web?
Should the overflow tank be about 50 degC?

There is a user book
And a Installation Book / manual.
Have you both?
Yes the F & E tank will be quite hot.
More so if venting over etc.
Ned to check it out fully.

Checked the tank and it had a fine film of sludge on the bottom.
While we were away the top was blown off the F&E tank and there was rusty water down the cupboard wall, less than a gallon.
The piping system was partially drained and a cleaner added which is now circulating. Last night the loud rumble returned at about 20 min intervals until I switched it off.
During this period the water was topping up a small amount.
This morning switched it back on and it sounded like air venting through the pumps.
Currently no recurrences but the message on the readout S1/S2 is F. with an L above a _ . Can't find out what this means.
I will get the system completely drained and new inhibitor added.
Any suggestions.

Sorry I do not understand your message.
Page 31 of the book shows the Display and what the unit is doing.
H2.1 means PHE pump on. And so forth.
Pages 9 & 10 are ref the fault codes and how to go through the ACB.
Are you able to go through the fault codes?

When I push S2 the readings do not seem to relate to the diagram on page 9.
I get CO 33 and cO 33, then F, then 5.1 75, then 5.1 68 then back to CO.
What am I doing wrong

C.O reads 33
C.1 reads 37
All the rest read FF
37 reads S1 overheat 1 open on page 10
Could you explain what that means and what I need to do

Over heat sensor is faulty so replace.
Have you checked the unit is full / takes water?
Have you checked the boiler pumps spins etc.

Hi Mike,
Thanks for replying to my queries. I really appreciate your help.
As you probably gathered I didn't know about my Boilermate, but I have learned quickly, and your advise has been invaluable.

I presume the fault codes in Lock Out and Block Out are the same.
The readings seem to change C0 and C1 vary between FF/FF and 33/37, whereas c0 and c1 are consistent at 33/37.

To change the S1 overheat sensor I presume this refers to the part listed as key 14 in the Short Parts List (page 35).
For location of S1 I presume that I follow the wiring back from J9, connections 6 and 14.
I will get a plumber to change it out.

I tried resetting Appliance Type following the instructions on page 9 to A01. However I still have the error code 33, but the system operates.

You mention checking that the system is full of water. After draining down using the drain on a ground floor radiator to add the cleaning solution the system was filled from the water feed to the F&E tank and the radiators bled twice. Is there any other way to check that the system is full.

I checked the pumps by feeling for vibration when they are operating , but can't feel any. All the casings and systems are hot.

Lastly can you recommend anybody to carry out the work and check out the system generally in the Ashbourne area in Derbyshire. I think that you are located in Norwich.

Thanks again,
Roy

Over heat sensor GT 199 is located top left on the unit.
Pull it out. Unplug. reverse order fitting new one.
Switch unit off whilst fitting.
Fault codes will stay on the ACB will drop off when they get to 16.
33 is appliance selection.
In relation to the ID resistor located at J9 on the ACB (top) yours should be white and the code is A01
So check & re do that.
Do that by undoing the big screw on the front of each pump.
Look on here Home page list of advertisers.
Or Google up Gledhill repairs for your area.

Hi Mike,
I have replaced the overheat sensor (GT199) and the fault code c1 still reads 37, C1 reads FF. I pushed the reset button on the front of the unit and no change. Should the fault code disappear?
Still don't understand the difference between Lock Outs and Block Outs.
