Bosch Classixx Dishwasher Dy cycle not running

I have a Bosch Classixx Dishwasher SGS55C02GB/01. Runs fine except water never gets hot - never reaches dry cycle and will continuously run with 1 min left on timer - so wont drain and finish complete cycle.

( If reset button is activated it will drain ! )

Driving me nuts.

Cakeman - if you can help Would appreciate it.
I think it could be element or therostat - but dont know how to
get to it !

It could be several things: Heater element, NTC/thermostat, broken wiring/bad connection in the heater circuit, faulty pressure switch, or a damaged pcb. Your machine is fitted with the dreaded instantaneous water heater http://www.buyspares.co.uk/heater-element/product.pl?pid=922036&query=483657 The combi NTC/safety thermostat sits on top of the heater assembly & looks like this http://www.espares.co.uk/parts?k=189319 Both are mounted in the base & awkward to access, but this is your starting point. You need a multimeter, 3 hands, a box of plasters, plenty of patience, & a swear box. Maybe time to call service

Most Bosch machines I have looked at with failing to heat the water are due to the heater relay on the PCB failing.
Alot of the time it has been pretty obvious as at least one solder joint on the PCB relay has failed or dry jointed. Re-solder and ok after.
