Ideal Logic 30 - Not Working after removing Condensate pump

[Colin HD]

Hi Guys
Re decorating the kitchen and found an external gully almost directly under the boiler location.
Apparently the previous owner/installer didn't realist was there, because they ran the condensate into pump/trough and then up into the roof space and over to the kitchen sink!

I have removed/disconnected the condensate pump and run the pipe directly into the gully.
I simply removed the cables from the pump and put everything back together and now the CH is not working.
The HW works fine and kicks out some condensate, but no CW.

There is a Honeywell thermostat wired in and when you increase the temperature that is 'clicking in' but the boiler is not firing up.
Feel I might need to install a 'link' but cannot work out how /where.

Help would be great

time to call a gas safe eng out i think but

you didnt remove anything looking like this did you?

or if wired what model no of room stat have you got

Recent installation???

 

[Colin HD]

No, I didn't remover the receiver unit, just the pump power supply and High Level(?) wire.
Installed in 2016, or thereabouts, paperwork came with the house sale, but will have to check.

 

[Colin HD]

Sure it was a Grunfos pump unit, can check when I get home.

Sorry install 2013 not 2016

High level wire ? did you disconnect it from any controls ?

if the pump fails it is run in series to the boiler to prevent the boiler from working, by removing the pump you have effectively left the circuit open so boiler cant work, call a sparky with a meter to sort it, you do not need to go near the boiler to make it work.

reread, thought the whole thing were down probably caused by that bit of wire hanging off the ceiling, nothing to do with condensate pump removal, red herring n all that

 

[ShaunCorbs]

and, the pump is wired to fail safe, he has removed the pump!

but works in hot water normally pumps fail safe are wired into the power (mains) so if the pump fails the boiler doesnt have power

if its wired into the central heating its been wired wrong

you never know

true and tbh most are left off as people dont know how to wire them
