Re: indesit wd125 error code?? three flashes

As Dave says its almost certainly a OC thermistor / wiring fault.

Easist way to check is to slip the plug of the thermistor and measure (using a multimeter) the resistance across the plug terminals. If there is no open circuit (broken connection) you should get a reading of about 13k ohms through the module.

The thermistor itself should measure about 24K ohm at room temp.

Re: hotpoint WMT03 1400

Betcha its a wiring fault, especially if Hotpoint have replaced the drum at some time and not replaced all the tie wraps. Easiest way to check is to slip the motor plug (X1) off the module and check for return continuity through the motor. Be careful to exclude the interlock connections (three) which are on the same plug. One of the tacho wires will probably be O.C. so there will be no continuity across two of the connections.

Re: Expensive Mistake.

I have had loads of problems with faults caused by the chafed / broken wiring on WMA’s. Most of the time it is due to hotpoint engineers not replacing all the tie wraps when they have replaced the tub (bearings). Its the first place I look for a problem / cause of a problem on these M/C’s.

Re: Fisher Paykel smartdrive motor controller

If there is no device number on the DSP / MCU chip then it is probably a specialised device, although why is another question, as these programmable driver IC’s are readily available from many of the manufacturers. In fact it is the development of these driver IC’s that has made the use of this type of motor economically feasable in domestic appliances to achive complex electronic commutation at a realistic cost.

There is no reason why a control device from an other manufacturer (with full info available on interfacing and programming) could not be used with the existing inverter, as motor control is achieved through six outputs to drive the inverter stage, three inputs from the hall effect sensors and possibly a PWM output to a power factor correction stage, although this may not be implemented on small motor inverter chips.

Programming probably involves flashing the required sequence and timing data into an eeprom.

Whether it is possible to achieve step control of these motors using these driver IC’s is another matter?

Another possibility which I have been contemplating is control using a PC’s parallel port, some circuitry may be needed to adjust the levels to that required by the inverter inputs but should’nt be too difficult (might be safer to use an opto isolator stage). Then it is just a matter of writing the software to read the hall sensors for positional data and and send pulses of the required timing, duration and sequence to each of the invertor inputs. This would probably have to be done using for eg. C+ as I don’t think that Visual basic has easy access to the parallel port.

Control as a stepper motor could be easily achieved using this method.

Just for those who might not know – the inverter stage usually comprises three sets of power transistors (either bi-polar or MOSFET’s) each of which are configured as two devices wired in series. This configuration allows each pair to either source or sink current and allow the current flow through the coil to be reversed. The coils may be either star or delta wired. So a rotating magnetic field is achieved by turning on each of the power transistors in the correct sequence.

The pulse sequence and timing can easily be obtained from many of the data sheets for these devices.

Re: Dear BSH-Man…..

I have found this a fairly common problem on the WM series too – no Neutral supply on the interlock due to a narrow blown track on the PCB.

Cause faulty interlock.

Re: HOTPOINT WM62P TIMER/MODULE

Have a look at Pats experience here:-

http://www.ukwhitegoods.co.uk/modules.p … highlight=

Now this guy had’nt even done anything wrong! – Some people are not very nice and take great pleasure in trying to screw you for as much as they can get just for the hell of it!

I have had people try to set me up in the past. Went to a T/dryer found the heater and wiring burned out due to a bypassed TOC. Next day got a phone call saying that there were three people that were willing to swear in court that there was nothing wrong with the machine before I touched it!

Not worth the risk IMHO

[andy2]

Re: HOTPOINT WM62P TIMER/MODULE

Chris – I was’nt implying that the timer might be non-gen but that because the part number is not the same as the original an insurance company would eagerly use that fact to prove that the wrong part had been fitted.

Andy 🙂

[andy2]

Re: HOTPOINT WM62P TIMER/MODULE

My advice is to backheel the job. Fitting any non-standard part is not a good idea, and would probably invalidate your PL insurance in the event of a claim.

If you want to take the risk, then make sure you get it in writing that she is supplying the part and takes full responsability for any damage done to her machine or property.(but I don’t think that this gets you off the hook)

This may sound extreme but I believe it is always better to err on the side of caution. (cover your own backside in all events) 🙁

Andy 🙂

PS. Incidentaly this raises a question I have sometimes pondered – is the fitting of a non-gen spare classed as fitting a non-standard part?

mmmmmh!

Hope there are no Jewish engineers reading this, they might take exception to you attributing a ‘Christian’ name to a Jew.

Re: Pay as you go

My understanding of the Galileo GPS system is that this is a GPS system similar to the US version. The main drive behind GPS is military and always will be, hence the ‘M’ code which virtually renders it unusable to others if it implemented (which is a pity if you happen to be on a yacht in the middle of the Pacific when the conflict starts).

The question must be asked ‘Why would the EU want its own system anyway’ when there is a perfectly good one in place already. The obvious answer is independence from the US and the ‘M’ code should the situation arise when the yanks pull the plug.

My point is that GPS was not initially developed to be a surveillance system but a miltary aid, to complement the very effective visual satellite surveillance that is already in place

If the Galileo GPS system is able to be used in this manner then there is no doubt that it was designed to do so from day one and using it to monitor traffic movement is not some ‘afterthought’. If this is the case then it raises a mountain of questions that reach far beyond the issue of traffic monitoring.

This system is also a joint venture between many countries and I wonder what they will have to say about the monopolisation of the system by us Brits. Can’t see that going down to well!

Having said this I still have huge doubts as to the practical feasability of a system that is based on RF. because it is so easy to for the signals to be interfered with, both accidentaly and intentionally. Presumably these transmitters will have to be switched on all the time, otherwise the ‘authorities’ will never know whether you are ‘off road’ or whether you are ‘on road’ but not transmitting. This means that every vehicle in the country will have to be handled 24hrs a day by this system.

And this is until the Germans, French, Italians etc want to use it for the same purpose.

Will it be an offence if your transmitter stops transmitting? If so what about flat battery issues etc. The questions go on and on……..

Much easier to get the revenue of petrol and road tax and maybe put toll charges on certain stretches of motorway.

Unless there is a much darker side to all this and this is 1984! Maybe they really want to implant these devices in me and you. aaaaah!

Politicians – brain dead individuals that can’t do a proper job! 🙂

Re: Pay as you go

Would’nt worry about this one – its just the politicians spouting cr*p again.

We are not talking GPS here wherea few transmitted signals are recieved by millions of receivers. This involves two way simultanious reception and transmission between millions of motorists and ?? how many satallites.

Now I don’t know how many satallites would be needed in a system like this but i would bet that there is nothing up there now that could handle this sort of workload which would mean a wedge of new satallites at X million £’s each.

Even if it did happen the technology would be based upon high frequency radio transmission and the signal could be shielded, distorted or jammed to render the system unusable. If you have ever used GPS you will know that it is very easy to lose the satallite signals especially in city urban canyons. To actually purposely block the signal is very easy by shielding the device.

Six months down the road from this system being implemented you would almost certainly be able to buy dashboard devices that would make you invisible to big brother and thus running around ‘tax free’.

If you doubt this then have a look at the abundance of devices available today to thwart speed cameras, radar traps etc.

Even if there were precautions in place to warn BB of the loss of signal from your transmitter there would still be no way for him to prove that the device had not malfunctioned and that your vehicle had been sitting on your drive at home, or out shopping etc. Apart from alerting the police to look out for your car there is not a lot that could be done.

Where there is a will there is a way!

Re: Hotpoint FHP 1000-1200 motor

Just got six new ARM 20’s Qualtex price has gone up around £4.00 costing me £19.99 + vat ATM.

Looks like Qualtex is cashing in on the demise of the Gen part. To be honest I don’t blame them, they must have been pretty cheesed of when Hotpoint dropped the price of their armatures and we all dumped the pattern parts. I used to use the ARMQG1 off Connect, until the GEN parts dropped to silly prices, at one point I was paying about £12.50 + VAT each for five off!

A nice lady told me that Qualtex had discontinued the ARM20 but had since re-tooled to resume production (obviously because of the GEN situation).

I suspect that Merloni / Ind Co would like to jettison any commitment to Hotpoint / Creda spares for pre-Merloni machines, and that the dis-continuance of the armatures may just be the prelude to other lines suffering the same fate.
