vaillant 242E, 282E

[icecold]

Hi guys,

I have a 242e or a 282 e it lists both on the casing which wont supply hot water or heating ,all fuses are ok and the red switch is lite.

It stopped working after i turned on the hot water ..after this there was a banging coming from the boiler and now hasnt worked since please help,

had one guy out said it was knackerd and came to this conclusion in 20 mins with just a torch and screw driver, another guy tested tghe boiler and seems convinced the PCB are fauklty but advise i call vaillent .....anyone got any clues or the number to vaillant service.?

check the overheat stat bottom left on a chrome pipe hasn't tripped

what's the pressure

 

[gas4you]

Sounds like no flow through boiler. has anyone checked the pump? it may have gone to overheat.

 

[icecold]

pressure is 2bar....and when it did happen i noticed the temp gauge was near 90 degrees after i got to the atic

 

[gas4you]

about 90 degrees will go to overheat. Banging is usually no flow through heat exchanger. Check pump first. Do rads heat up ok?

 

[icecold]

no nothing the boiler is silent np pumps nothing work ch a no go to, once it over heats does it not reset its self?

 

[gas4you]

Has the pump been checked? Has it been checked power to pump?

 

[kevplumb]

once it over heats does it not reset its self?

no but you need to find out why it overheated

 

[icecold]

dont know what any of them did.....whats the normal fire sequence i.e pump then ignite fan etc...and how do i test the over heat trip?

no but you need to find out why it overheated

once they trip are they then replaced because last night i just bypassed it using a amp meter,

IM a auto electrician and have fixed my older boliers potterton but this is way more advanced. lol

 

[gas4you]

Call for heat, pump, fan, aps satisfied, ignition

 

[icecold]

ok so if pump is in op the system wont fire?

last night i just bypassed it using a amp meter,

bypassed what

last night i just bypassed it using a amp meter,

bypassed what

the smal black 2 wire over heat trip ,which looks much like the ones we use on wabasto cab heaters

 

[kevplumb]

you press the button between the wires

then power off then on

failling that get the pump checked
