Zanussi ZDT6244 Dishwasher Taking Too Long For Program.

[jonlfc]

We have a Zanussi ZDT6244 Integrated Dishwasher twhich is about 3year old,the past few nights it has took it nearly 180 minutes to complete the usual program(65oC).
This program only usually takes 70-80 minutes max.
There is nothing wrong with the cycle itself as all the dishes are clean and dry.
This morning i tried it on the lowest program the 30oC which usually only takes approx 30 minutes to complete,it took it 47 minutes.
Anyone any ideas please?

Sat and watched the machine as it is doing my head in.

The machine turns itself off, the power light goes off for approx 3-4 minutes every 10 minutes then comes back on, the machine then restarts itself,the machine is wired in properly what is the reason for this?

Possible that it could be a loose wire/bad connection on power switch or PCB

(wire making contact, as current flows while running it heats breaking contact cools back working again)

Not seen it often but it is a remote possibility
