little or no tech
they list a service manual but when i looked its for a gas hob

there are 2 power board but they are both the same so its unlikely for both of them to fail. each power board supplies 2 rings.

there is then a control board that controls the 2 power boards

when you say everthing works does that mean you can control all the rings but not heat comes out ?

bit like a demo mode

as long as its not one of the cheap makes will be ok

is that very old ?

get hoses with those doing this occasionally.

get some of the old Evo Stik impact ahesive. must be the old one with the strobg vapour smell. dry hose off internally and the spigot on the draw. smear a small amount of glue on the spigot and then slide the hose on, put the clip on and let it set

that will most likley sort it

dont use any other glue and never superglue . Its a rubber adhesive so you can take it apart again if ever needed

try one big long shot

find board and firmly tap each relay

then try it

if it works it was a stuck relay and it may happen again or it may not

you cant be certain of any board these days.
it can have all the right numbers but have different software loaded on to it

hope it works

Dave

well that may be it

you need to check power is getting in the machine first

check socket plugand fuse

on the late units F15 is a virtual sensor fault

Dave

[electrofix]

before you call it a day if you want

check all connection

check you have mains voltage on the board

make sure all your solder joints are ok and you have not damaged tracks

if it was me i would check for voltage both on the high voltage caps whicH should be 300v DC ( be careful( and the low voltage caps ( probably 12VDC ) but only if you are competant and safe

meter on low ohms scale
remove large side plug
test between the 2 terms where the red cables connect
readings below 100 ohms are ok

Dave

[electrofix]

well its not unheard of as the heater on these unit are very weak

if the water flow through the unit is too slow due to blocked bars or filters then these units can blow

there are other reasons but its a pity the older models almost never blew heaters

if you full model or pnc can look for any tech info
