ISE 1607W

Re: ISE 1607W

Well i recently bought 12 boxes when they were on offer 😯 😆

I use 55ml and the high-water-level option and still see plently of suds and as i said the results even on my sons filthy work clothes are excellent 😀

I live in a hard water area and i am only using 55ml of powder with superb results, the recommended amount is 135ml!

So if you live in a soft water area you can reduce the amount even further, down to 25ml in Brighouse, West Yorkshire apparently 😀

I would presume yours machines are suffering over-foaming if you are using the recommended dosage by the manufacturers, if i, in my hard water area, can reduce my powder so much and still have excellent results 😀

Best wishes to all,

I wonder where you got that from eh, quickwash………. 😆

Re: ISE 1607W

Thanks for all the replies and help but I am still not convinced it is anything to do with overloading or too much detergent.

Let’s just suppose the machine was overloaded for a moment. Surely if the machine is overloaded no wash programme would work? The same thing would happen – machine just sticks. Yet, I drained the machine, did an 800 spin and then set it on a Quick Wash with no detergent and it all worked fine. I took no clothes out (as I didn’t think it was overloaded) so the machine had the same weight of clothes.

I never put in too much detergent as I said before.

Surely if the machine is overloaded on one programme it must be overloaded for all of them?

Very unlikely to be overloading, very likely to be oversoaping. 😉

Re: ISE 1607W

Not convinced it’s oversoaping either as I put very little detergent into my washes, also very tiny bubbles in drum not huge soap suds. I must put about 60ml in, with measuring jug.

Re: ISE 1607W

You say you don’t think it is oversoaping but you also stated that you
‘then set it on a Quick Wash with no detergent and it all worked fine’.

Re: ISE 1607W

I’m obviously not going to get anywhere with this problem. I know the machine WASN’T overloaded and I know I didn’t use too much detergent.

I am extremely disappointed that I have not received more constructive support from UKW.

Re: ISE 1607W

Okay, so what happens in most all modern machines (I know of no exceptions bar toploaders) is this…

The machine fills with water to a preset level.

That level is determined by a pressure switch, these days an digital pressure switch that reads infinite range pretty much so far as we’re concerned, so that the machine can adjust the water load to the load of the clothing.

The water load will vary depending on the program, volume of laundry and water retention of the laundry in the machine. So, three variables that can change wildly from load to load. It is bordering on a miracle to have two loads the same.

In order to do all this and have the machine calculate the most efficient use of water an power usage, the pressure sensor and its accuracy are vitally important. To achieve the modern requirements on energy use there’s pretty much no alternative.

The fly in the ointment of all this new found efficiency is that the sensor can be “fooled” if you like by oversoaping.

The sensor (which is basically an air switch) is fed by a thin tube that runs from the sump to the sensor. The air pressure as water fills the tank and therefore the sump causes a change in the pressure of that air that is detected and read by the sensor. This is reported to the control PCB which determines when to stop or start filling.

Where overfoaming or oversoaping causes an issue is where the foam gets trapped in that tube. The electronics then thinks the machine has more water in it than it actually has as the pressure doesn’t drop as the machine empties.

We refer to this as sudslock. The reason being that the soap suds “lock” the pressure sensor into falsely reporting that the machine has a water load that requires cleared but, try as it might, the machine can’t clear it.

Ultimately, if it tries again and again and can’t clear it most machines will report a failure to drain even although the machine will appear to be drained.

The only cure is to reduce the detergent dose as this is exactly how the machine should operate and, for safety’s sake, it has to operate as the alternative in overriding that control isn’t pretty.

However, the 1606 and 1607 are both also protected by a safety overfill protection device which is an analogue pressure switch. This is an emergency measure not found on many machines these days to protect from overfilling. It’s a double safety basically, but the secondary pressure switch only kicks in if an overfill is detected.

Is that enough of an explanation and is it understandable? Apologies if it isn’t as it’s a hard thing to explain at times and why the machines do what they do.

Re: ISE 1607W

Sorry, I forgot to add that, as the machine does all this it will try to recalculate the estimated end time and, if it can’t then like most electronics, the display shown in terms of time may not be accurate. In fact, it’ll probably be wildly wrong.

Think along the lines of, if you get caught in a traffic jam when using satnav, the satnav can’t calculate how long you’ll be stationary and gets all confused so makes the best guess it can. It can’t factor in things that it can’t know basically.

Re: ISE 1607W

Thank you and yes I do understand it.

In order for the suds to cause this blockage what amount of detergent would you need to use in a reasonably soft water area?

Would you expect to see a lot of suds in the drum?

Would an error show on the display?

On draining the machine and spinning (as I did), how much of the detergent would be discarded during that process?

Re: ISE 1607W

To be honest, that’s almost impossible to answer.

The three variables come into play and more, water load, water temperature, laundry load, detergent used, water hardness, previous residues and fabric in load off the top of my head.

If there’s any more than about 1-2.5cm of foam, it’s too much.

But, in a soft water area this is very common on many brands these days as water levels are much lower now than they were. With soft water you need to reduce the dose considerably anyway, even on an old machine here we were using half the recommended dose or we were getting too much foam building up.

No error would be displayed until the machine gave up completely on trying to sort the problem out of it’s own accord and, it will try for a while.

By how much detergent discarded do you mean wasted as in unused? Again incredibly hard question to answer as it would depend on all the variables.

Re: ISE 1607W

Start with 25ml of powder as used by Oliver (Higher-water-level) who lives in a soft water area and reports that his ‘dirty work clothes’ are still washed properly. There is a thread on here but i dont know how to do that quote thingy :rolls:, I will post on it and bring it up to the front 😆

As i have mentioned before, i live in a hard water area and i only use 55ml of powder and my sons (mechanic) oily work clothes are washed much, and i mean much, better than in my previous machine using 135ml of powder!
