SOURCE: ariston micro genus combi boiler

having found a circuit diagram, realised that the divertor valve was electrically operated.i unplugged this then unclipped the motor from the valve body,the diverter valve is spring loaded and once i'd removed the motor the spring raised the valve to divert water through the dhw heat exchanger,giving us hot water but no heating, if i refit the motor the problem comes back heating no dhw.ordered new motorised valve assembly £30 next day order .
this was a simple fix without having to drain the system down.

SOURCE: blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.

Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

Sorry Terry - I'm not used to this site! Question was - anyone know what the error message E34 means on an Ariston Boiler MicroGenus 24HE please?


The information I have found states it is a problem with the pressure switch. A faulty pressure switch will prevent ignition from occurring. Here is a Youtube video link showing the issue. Reading the comments below may assist you in isolating your problem. Hope this helps!

I have a newlec timer channel plusxl model nlh37 unable to programme it after it was switched off, all heating systems running at same time


1) Power surge such as turning power ON can put out timers.

2) Reset timer, and if functionality is not restored, then replace timer.

3) These timers usually have 1 year limited warranty.

4) Add comment and include photo of timer. And post your .pdf manual on your website, and include link to manual so timer and steps for reset can be ascertained.

Hi, I am having problems with the timer that controls my boiler. It is a 'Lifestyle LP522'. The hot water is set to come on in the morning for 4 hours and again at 4pm for 3 hours. The heating is...


then there must be a problem with the programmer as the boiler thermostat will call for heat only if the programme is on try setting the water side to 24 hrs it won't cost any more to run , but will prove if programmer is working .

I have a EC4000 electronic digital timer. The problem is when the timer hits a preset time to turn the boiler on , the boiler will not turn on, but when I hit the manual override button on the timer the...


Paragon EC4000series are programmable timers
EC4000/120 for 120V
EC4000/277 for 208-277V
dc5a40e.jpg

Is this a new installation?
Or was timer working fine until recently?

1) With digital programmable timers like EC4000, if there is conflict in programming, or missed program, then timer might skip the program.
For example if program1 says ON at 7 and OFF at 8, and program2 says the opposite.
2) If wiring is reversed, then the manual override will work but clock will not operate, and the timer will not function.
a) for 120V timer:
-120V black wire from breaker goes to terminal2
-120V white wire from breaker to terminal1
-jumper wire from terminal2 to terminal3
-Load black wire to terminal4
-Load white wire to terminal1
b) for 240V timer
-240V Hots from breaker go to terminal1 and 2
-jumper wire from terminal2 to terminal3
-Load wires connect to terminal4 and terminal1


Below is link to EC4000 instruction manual
http://waterheatertimer.org/pdf/Paragon-EC4000-program.pdf
Troubleshooting steps say to review set-points.

Solutions:
Checking wiring as described above
Check programming.
Reset timer and re-program set times.
