I have a problem with a Vaillant Turbomax 242E pilot solanoid is not being energized. All other functions seem to be working fine. I.E. fan ignition etc. The ignition sequence goes all the way and sparks at electrodes but the solenoid does not energise. I have changed the solenoid and changed the main board. Any suggestions please.

There are 2 solenoids on this gas valve the one I have replaced is the lower one part no VAI17-0365. When the solonoid is removed it is possible to manually operate the gas valve which seems to be woking fine. unfortunatly there is not a flame suppervision board on this model.

get a gas safe engineer as this is a specialist job.
Bit painful after spending about 200 squid and a day's work, if not more.
I am a retired gas engineer (corgi 25474) working on my own boiler,how ever I have not encountered this problem before. Any more relevant thoughts would be appreciated. I have E mailed Valliant but to date have not received a reply.
which board did you replace? what voltage at the solenoid? Is it locking out? Is there any noticable change in inlet wp during sparking... not sure if this is suitable conversation for open forum....but hey ho..
Hi
I changed the main board not the switch board. Voltage at solenoid is 14 D.C no change in working pressure at ignition. Voltage is listed in service instructions as 20 D.C This could be the problem I do not know what could cause the loss of voltage.
