Cold fill only washing machines

MATH

Even the machines with hot and cold fill usually only cold fill for wash temps set at less than 60 c. Temps above this get a 50/50 mix which taking into account how little water these new machines require and the hot water that has cooled in the pipes being drawn into the machine before the hot the starting temp is tepid at best requiring the internal heater to boost the water to the correct temp during the wash. I doubt most people will notice any difference.

When we bought our energy saving AA machine in January that too didnt have a hot water inlet. We just turned the hot water tap off behined the machine under the sink.

i think they have gone over to cold fill only, as most modern houses have combi boilers, and you can only use cold fill machines, on that type of heating system

personally, since having a cold fill machine i have not noticed an increase in my electricity bill, but my gas bill has come down considerably since fitting a combi boiler

I had noticed years ago that of the many countries that |I was luck enough to live in the UK seemed to prefer hot water washing. Now I don't want to interfere in pink jobs :rolleyes: but it was my observation that cold water seemed to wash just as well. Maybe this link will help:

As with dish washers - the vast majority of washers & washer / dryers are cold fill only. It's mainly to do with efficiency and getting the right temp water for each wash type - as opposed to whatever temp your hot system decides to give it. And the fact the modern machines use much less water than previously.

But whatever you do - don't connect the hot to the single inlet as one suggestion. It won't do your clothes much good, let alone the washer and the warranty.

Equally don't re-use the flexible cold pipe from your old machine. The new ones tailored to fit and has new sealing washers etc. It's only a 'just past finger tight' to couple both ends - so it's not going to be difficult to do it right.

But I would cap the now unused hot fill. Presumably there's an isolator in the pipe and they're reasonably safe if it's the type that's turned by a screwdriver. But if it's a 'hand job' ('scuse the expression) then it can be turned on by accident - or the machine jumping around if it's behind it. So, safer to put a 25p brass cap on it rather than risk a kitchen full of hot water?

My cold fill machine clogs up the powder drawer but as the previous post has already said,liquid works out quite a bit more expensive.
I got round this by opening the drawer a bit when it is first switched on and flushing the powder in with a litre or so of warm water .
I thought it probably helps it to come up to temperature quicker too.
Seems to work but I don't know if anyone else knows a reason why this is a bad idea!

I dont think thats the reason, because our old machine worked fine with a combi boiler. The lastest boilers are now condensing boilers, we have just recently got a new one. Gas is cheaper to heat water though than electric is.

Where did you hear this? I don't remember reading anywhere on my washing machine instructions that I couldn't use it with my combi boiler. What damage could I be doing?

We have a combi boiler and the washing-machine that just got replaced was hot/cold fill, with no problems. I think flea72 may have got his/her wires crossed on this.

the manual with my boiler states it must only be connected to cold fill washing machines.

and i think the manual with the washing machine says that if you have a combi boiler, only connect to the cold fill

i dont think it will blow up your boiler if you have it connected to hot and cold fill, but there is obviously some reason why they suggest not to connect to a twin fill washing machine

it may be similar reasons to why you shouldnt connect a power shower to a combi boiler. im not a plumber so cant define the logic, but am just going with the warnings that are given for my system.
