You will only blow the meter if measuring too large a current,and even though,fluke meters are fitted with quick blow fuses! Heres a little tip on how to check the internal fuse. 1. meter on resistance 2.red lead plugged in to volts/ohms position. 3.insert black lead in amps position...

I know the one mate.I have checked continuity a million times.On off on off on off.

Bingo. After finding out about the difference in models ie. flow switch/pressure switch finally i have found the fault. Initially i looked at the installation manual followed instructions for low pressure-code 04- I then found pressure ok Checked what i thought at the time was the...

I hear what you are sayin scatman,but i can physically see the pin from the diaphram move back like no flow. I have the boiler cover off just now im goin to check voltages at pump when fault happens. It seems to be doin it less frequent now!!

It appears after much searching,there is 2 models of this boiler.An early type with a flow switch and a later type with water pressure switch! Does the flow switch only activate when the pump is on.If the pump is sticking will i stil see voltage at pump even if flow switch has shut off?

I had a similar fault with a mira sport shower. Low pressure then the overheat light came on.No matter how much i cleaned it the only solution was a new water flow valve(pilot valve). I am no expert here mate,just sharing my experience.Hope this helps.

Cheers bud. My heads bursting thinking about this! Maybe i should get an engineer in here and be done with it.I am a motor mechanic after all! :lol: I just like to know a little on how thing work!

I see. The vokera linea 24 is a discontinued range. :oops: old as the hills probably!! In the manual it states there are safety devices. An electronic device that checks the primary pressure unit for activation.Failure results in de activation of the pump after approx 10 min of...

No worries bster.I appreciate your input. 8) I am sure the diverter is different to the pressure differential switch mate.The diverter is operated electically by motor and seperates DHW and CH. Correct me if i'm wrong as i am basically trying to understand and teach myself here! It is...

I have looked at the boiler again.There is no seperate pressure switch other than this diaphram one guys??? Could i have a faulty/sticking pump?It seems to me that when the heating is selected the pump runs then the switch is pressed? Man this is annoying :roll:

Yes i noticed there was a drilling on the cover behind the diaphram.This made me wonder what this was for.Its becoming clearer that this may be the way the PRESSURE DIFFERENCE is measured. Yes the water and heating work fine for a while then trip regardless if heating or water on.

I have to admit it looks different on the boiler than it does on the installation manual,but it is in the same position at the right of the pump. My local dealer(HRPC) do not list a swithch for this model.I reconed it was due to it being this diaphram type with externally mounted switch. I...

The instructions say water pressure problem and refers to filling of system,which i have done and set to 1.5 bar.(it was at 1 bar previously). Let me get my head around this.Pressure is in the radiator side of things?Correct? If so this should not affect the DHW? I can set the boiler to...

Hi Can any one lend advice.I have a vokera linea 24 combi.Trouble is it keeps tripping after 30 min flashing fault code 04.I have set water pressure to 1.5 bar,checked diaphram at switch and have changed the pcb with no success. Possible water flow problem? Sometimes it does not reset for...
