Since I had a Combi fitted in the loft, I have noticed that
a) my electric shower now runs fine,with no need to turn it on for approx
5 minutes,
to give it time to stop blasting freezing then hot water, alternately and
b) my washing machine now does its final rinse in very hot water.. If I am
around when a
cycle finishes,
the clothes are steaming hot.. On a 40deg wash, I could end up with
shrinkage, etc...


Does the boiler fire up when the washing machine is doing its 'cold fill'?
Likewise, does the electric shower cause the boiler to come on?

Are the taps to the washing machine properly connected, and any valves
turned on full?

Have you got the hot and cold inlets to the washing machine connected
correctly? If they are swapped (red and blue hoses to the machine) then
the rinse will be from the hot water supply and not the cold.

If you can gain access to the back of your machine feel both hoses while
filling up on a 65 degree wash. The blue hose should be connected to the
mains inlet and should not be getting warm
and the red hose should not remain cold.

swop the fill hoses round they are indeed reversed

Logic would suggest that the hot and cold feeds are reversed on the
washing machine - disconnect it and run each tap in turn into a bucket
(or the hoses into the sink if they'll reach) to see which one runs hot.
Don't know about electric showers.

Pretty much what I thought, except that I haven`t altered the way the pipes
feed to the washing machine & it was ok before the combi was fitted.. Perhaps
the plumber disconnected/reconnected for some reason..? I will certainly have a look
when I`m able to access the back of the machine(not an easy job!)
Thanks for all your replies

cheers

That can still be correct but if the hoses are crossed on the back of the
machine it will still be wrong, best to put machine on rinse and check it
fills cold only.

1. Does the combi fire and run when the electric shower is turned on?
2. Were the hoses for the washing machine installed before or after the
combi?

If 1. is yes or 2. is before the combi then call the plumber back, as he as
made a boo boo!!

Some washing machines do a warm rinse last, candy washer driers to
name one. It may be a case of throttling the hot water feed or fitting
the restrictor washer in the hot inlet, to reduce the amount of hot
taken with the cold.

Don't machines have valves on the inlets which are controlled
automatically to mix the feeds from the hot and cold?

The piping to the washing machine (from the combi) may be shorter than
the piping from the hot water tank was.
This means that when it draws water to rinse, it gets hot water, rather
than most of it being stuff that's sat in the pipe for half an hour and
gone cold since the fill.
A diagnostic should be to do a boilwash.
If it takes a long time to raise temp, and starts out cold, when it
should be taking in hot water, then it's almost certain.

I don't think they really mix it (although I suppose posh high-tech ones
might), they just use hot water for a hot wash and cold water for
everything else, adjusting the temperature by heating once the machine
is full.

a) my electric shower now runs fine,with no need to turn it on for approx
5 minutes,

As for the electric shower, if I had a combi boiler, then the electric
shower would already be in the bin. Replace it with a thermostatic pressure
balanced mixer shower fed by the mains cold and hot water.

"no need to turn it on for approx 5 minutes" means to me that the combi
isn't quite adequate in terms of temperature.

Sorry, should have made that a bit clearer-prior to Combi installation,
the electric shower was VERY temperamental, needing 5 mins before
it stopped alternating between extremes of temp and now it runs fine,
heats up instantly.. The plumber didn`t suggest using my Combi for the shower as well,
instead kept the electric one as a backup & its fine for just me, anyway.

Still not managed to suss out if the Combi fires up when washer fills up, nor if the
hoses are crossed over, but at least I have a starting point..

Remember that your combi boiler will provide a shower that is an order of
magnitude more satisfying that a crappy electrical shower. The only reason
to have an electric shower is that you have neither gas nor space for a hot
water cylinder.

Or that you want to boost the flow from the combi in cold weather.

Quite a dangerous way to do it, though. The electric shower doesn't mix cold
in, so could easily scald by heating water that the combi might be providing
at 55C at low flow rates. Far safer to use just a thermostatic pressure
balanced mixer. 28kW gives an excellent power shower, even in winter.
