Re: Smeg DWI710E1 4 to 5 hr to complete a wash

OK – thanks Ken for that, very much appreciated.

There are codes for fill and drain timeout’s and it is heating OK so you would think that if there is a problem it would show up.

Might try a module reset but apart from that ??.

thanks again

Re: Smeg DWI710E1 4 to 5 hr to complete a wash

I considered that Ken but don’t these machines have a fill timeout error?

Re: Zanussi ZEBF249W f/freezer

Ok – thanks for that. I discounted a blockage as the air flows through the outlet with the freezer door open but i will certainly check it.

Re: What resistor do I need?

Hi Martin

I am suprised that you don’t already keep a few of these as they are/were used on lots of modules especially those using the common TDA1085 motor speed control IC. This was the recommended value for use in the power supply. They are often the culprit if the board is dead.

Seme do these at 11p each (min of 10) (AX5W 5K6) or a 7W at 19p (7W5K6). Seme only have a £10 free carriage threshold.

Somebody also mentioned Connect RC55K6 but these are about 45p each (ouch!).

Re: NTC – what is it and what does it do?

Hi Chris

A to D converters use the same comparison techniques each succeeding stage using a higher /lower reference voltage. The difference being that the comparitor outputs (which swing rapidly between two values (on /off) are combined to produce a digital representation of the analogue value that is of use to the processor.

A thermostat has just one pre- set cut-off point whereas a thermistor’s (NTC) temperature coefficient (resistance) can provide a digital electronic control system dozens of temps from the same device!

Yep. The voltage value derived from the resistance is converted to an equivalent binary value in an analogue to digital converter on the microcontroller chip. This value can then be compared against a binary constant which is representative of the required temperature until the two values are approx equal.

The same technique is used on some program selector switches eg. GIAS

Each position of the switch selects various combinations of tiny on chip resistors which returns a unique value from which after A to D conversion the switch position can be determined by the microprocessor.

Re: indesit W103UK module

These are the connections on CNF

1 Pressure s/w
2 Pump
3 Pressure s/w
4 Interlock
5 Pump
6 Heater (black)
7 Interlock

(Note:- 5 & 6 are commoned on the module)

If its water damage then this is irrelevent but it might be helpful.

Re: indesit W103UK module

Hi John

If there are signs of leakage i would not replace until you are certain that there is no leak onto the module. When you get blown tracks and/or componants it is usually from a peripheral componant that has gone belly up OR water leakage onto the module.

Which edge connector is burned out (CN_?) as this may provide a clue.

Re: MD Monthly Update

As the warranty liability was my only concern I would like to try and sell some ISE (if thats OK with you guys). I hope this new development will encourage others (who had similar reservations) to do so too.

This good news actually deserved its own thread.

Is this in place now?

Re: Lux ER2656B F/F evaporating tray

Hi – thanks for the reply but that is not the correct part. I found that on connections myself. The actual part is called the defrost tray but cdsl got back to me and apparantly it is obsolete so i am going to have a go at repairing the old one.

Thanks anyway

Re: Bosch WFB2004GB/33

Thanks Martin very much appreciated. It is not obvious on these how they come off and with the cost of a new one being £77 i did not want to risk breaking it. 😥

Re: Zan WJS1465 – Intermitant Pump?

MickGeorge wrote:Also anyone had the module cause an intermitant pump prob?Thanks guys.. 🙂

Unlikely, unless there is a bad connection on the edge connector or a dry joint on the little triac. Most of the pump triacs used are rated at 0.8A and Pumps are around 30/35W or around 0.2A so there is plenty of spare current available.

Re: no phone line on new computer

The man in PC world needs to find another job :rolls: Broadband and telephone work on two different principals even though they share the same line, which is why you need the filter to channel the correct signal to each device.

Whereas ADSL uses digital technology, modems (modulator / demodulator) actually send audio frequency signals down the telephone line (like your voice) after being converted from its digital equivalent on the computer. At the other end it is demodulated back into its digital equivalent before it passes back into the PC.

Lots of new machines are sold without modems now (unless its on the mother board) because its old technology. That is unless, like yourself, you want to use it for faxing or to process incoming calls etc.

Like i said a 56K PCI modem is cheap so get one and pop it in and Bobs your uncle as they say.
