Creda C366e Timer Fault

[Rbz5416]

I’ve had a few random instances of the main oven cutting out & the clock display flashing Auto. Both the element & fan cut out. Pressing Manual restores operation but with the clock reset to 00:00.

The same symptom has started happening when turning the main oven control back to Off when cooking is complete.

Re: Creda C366e Timer Fault

therev are only 2 reasons why this could happen

1 faulty clock
2 faulty mains supply to the oven cutting out just long enough to set the clock to zero

if it is the clock it can be electrically bridged

Re: Creda C366e Timer Fault

Thanks Dave.

I’m not sure about the supply although it did first happen after the kitchen was refitted & a new supply run from the consumer unit. But is was quite some time after. It also appears that a momentary break in supply isn’t enough, it needs a break of around 5s before the clock cuts out. I’ll have to open the fused switch & check out the connections.

The only other instance of this I could find online also suggested bridging the timer. But that thread was four years old & the OP never updated. Do you have a link to a PDF manual showing access to the timer please?

I only use the timer as a countdown & not for any automated actions, so bridging it wouldn’t have any impact on use.

Re: Creda C366e Timer Fault

if you post a picture of the back of the timer will try to tell you which ones to joint

Re: Creda C366e Timer Fault

Thanks but I have no idea how to gain access to it.

Re: Creda C366e Timer Fault

if its the one i think it is with the clock on the front panel start by taking off the sides

Re: Creda C366e Timer Fault

Thread resurrection.

Decided it was the controller so ordered a replacement (6201383). Now I have the cooker in bits, the parts are different. The original part is ET51001/J5.

Can anyone advise if this is just a replacement design or do I have the wrong part? If the former, can anyone help with wiring as the terminals are labelled differently. The original also seems to have a bare wire in red sleeving attached to the body.

Re: Creda C366e Timer Fault

A 6201383 is not a control timer, it is the small switch bank that sits in front of the main oven stat, is that what you mean by ‘controller’?

There are two different control timers used on these cookers, full serial number needed to ID correct part.

Re: Creda C366e Timer Fault

Thanks. Terminology always an issue in these circumstances!

Maybe I have the correct part after all. The thermostat does seem to have two screws going through to the switch, but the switch again looks different. Parts 117 & 118 on your diagram, but I’d assumed it was a single part as there are no separate connections to the switch. I’ve hopefully attached a pic of the original setup.

Serial no. is 504140051.

Does the symptom described suggest one part rather than the other in your experience?

Re: Creda C366e Timer Fault

Part 117 is a small bank of rotary switches, part 118 is the main oven thermostat.

Reading the earlier part of this thread it was suggested that the control timer was the cause of your problems, not the oven selector switch or the thermostat?

That thermostat should just slot into the back of the selector switch. There should be wiring going to the rotary switch.

Sadly we do not have access to wiring diagrams, unless you know a friendly Indesit/Whirlpool company engineer you will struggle.

Re: Creda C366e Timer Fault

Well the fault increased to the point where it could be fairly regularly reproduced. There seems to be a point of rough travel just before the off position of the main oven control. When crossing that the timer would cut to auto mode & start flashing. So it seemed a reasonable diagnosis. I didn’t realise there was two parts to the control though.

But having said that, there is no sign of anything in front of the thermostat & all of the connections are on the thermostat itself, as can be seen in my pic. The top oven control however does seem to have something resembling the switch in front of it, which doesn’t match your diagram. So I’m a bit baffled by that unless it’s just a design change.

But it looks like I need a thermostat rather than the switch. But while I have it disassembled I may as well see if it’s serviceable.

Re: Creda C366e Timer Fault

Well having opened the stat there’s not much in it. The notched travel I was speaking of seems to be the breaking of the contacts at the off position. The only thing that potentially makes sense to me is that as the stat it turned to off, the contacts are bouncing, which is throwing the timer. Does anyone with knowledge of how the timer & stat interact have an opinion on that?

If Dave is still around this is the best pic I can manage of the back if the timer for the moment. I’d rather fix it properly but bridging would do I guess.

Top right is a black wire. Bottom right is a red wire that loops round to a terminal on the bottom left. Top left is a white wire going to the stat.

Re: Creda C366e Timer Fault

to bridge timer join the wires on the left ( the white and the red underneath)

if you use a piggy back connector it can be restored easily at some stage

Re: Creda C366e Timer Fault

Thanks Dave. 🙂

Does my bouncing contacts theory make any sense to you?

Re: Creda C366e Timer Fault

no cant see how timer goes to auto by turning the knob
