Hi there…
I hope someone can help me identify what the problem is with my Dishwasher. It seems it’s not a common model, and I’ve had no luck tracking down a manual online. I’ll try and accurately describe the combination of lights, that I presume are an error code.
I have 4 vertical indicator lights on the left hand side of the unit. The first one indicates power, the second is for the clock/timer, then the rinse aid fluid warning light, then one for salt. Of these 4 lights, the first and third light is on, i.e the power light and rinseaid light.
I then have a horizontal display with 4 indicators, presumably to show the process of a wash cycle. The first picture is for the timer, the second looks like it’s for the first stage of the wash, i.e a picture of the water coming down, the third looks like it indicates the drying, i.e vertical hazy lines, and the 4th is a picture of horizontal arrow pointing to the right. Of these 4 indicators, a light appears over the third one, i.e the drying part of the cycle (I think).
Anyone have any idea? It initially happened during a wash where it seemed to have been stuck on a cycle for a very long time (I think I’d gone out and come home a few hours later and it was still on).

Hmm, can’t track down any tech info on this one at all. So – was the water hot? Programmes will often “hold” until temperature is reached.

I had one of those; dated from about 1998, a Candy machine by another name.
The most likely scenario is a faulty heater, or a dodgy thermostat.
I don’t think this machine was properly electronic, it had an electro-mechanical timer under its ‘push-button/rotary selector dial’, with a mixture of led’s for the programme progress indicators, and neons for the rinse-aid & salt lamps.
The ‘start’ button was not latched. i.e. you had to press and hold for the timer to impulse and advance into start. There was also 3, 6 or 9 hour time delay options.
The ‘arrow’ symbol signified ‘end of programme’.
There was a two-speed motor; a special button described in the manual as “Super Lavage” (Super Wash). (Known as HPS or somesuch on Candy machines). This gave a more intensive spray pressure for heavily soiled dishes. I usually left it switched on.
A half-load option fed the water to only one basket, was it the upper one?
There was also a ‘quick-wash’ programme, which had static heating for around 18 mins (no motor action). When the temperature was reached, one of the ‘clock’ symbols illuminated (I think it was the neon one), signifying the requirement to load dirty dishes and detergent. I found it left dishes wet (no drying).
Anyway, try this:
Empty machine of all dishes, clean the filter, the try the machine on a normal 65 degree Celsius without detergent. Allow the machine to wash for about 15 to 20 mins, then open the door and see if there is any steam inside. If not, there is a problem in the heating area or thermostat. It might not be the components themselves, it could be a broken wire in the door area (wiring loom passes by the hinge area, subjected to flexing and stress).
Power off before removing any covers.

Penguin… unfortunately I can’t remember if the water was hot at the time it got stuck on the cycle.
Trolobite… cheers for the tips, although I can’t actually do anything with it as this combination of lights appears as soon as I power it on, i.e turn the dial to a program number.

Hang fire then, Martin may be able to help out. This will probably be tomorrow owing to the Reading result…….. 😀

Sounds as though it is stuck… Have you tried cancelling the programme? I think you have to press and hold the start button, in order for it to advance its timer through the complete sequence: lights should click on and off, until finally, the ‘end’ led illuminates. Release the button at this point.
If it will not advance through that cycle, try switching to all other programmes and repeating my suggestion. (I can’t remember if there was a particular programme that was designated for cancelling, or if it applied to all).
A final suggestion is the flood protection circuit may have activated. This is a very basic system on this machine, meaning that there is no base plate to catch water leaks. Instead, a special pressure switch is activated in the flood condition: to release this device, you have to disconnect the cold fill hose from its tap, totally, then replace and turn the water back on. This should reset the switch.
