Just done it this weekend. One dud thermostat replaced and two jammed
off released but I'm going to have to get a man in to deal with the
radiator that wont heat up. Suspect it needs flushing Too arthritic
now to manage unscrewing it from the place its in.

Mine was trying to light a couple of times, then made a massive vibrating
noise through the wall.
It sounded like it was blowing flames out. The boiler was only serviced a
month or two ago and
is only a year old now, so no problem with it, just a bit odd in it's
behaviour.

Nor me but that is normal, it's what thermostats are for! And as we've had
such an abismal summer it's had enough excercise to keep things moving(*).
A decent summer and the the stat will have it off all the time for a fair
while, maybe a couple of months.

(*) Must remember to do the gate valves.

Sound advice.

After a winter with intermittent problems followed by a blown PCB, we
tried to fire up the Potterton Combi 100 for the CH after the summer
layoff and it keeps on locking out. It fires up, sounds like its
boiling a bit and then switches off. Then tries again and locks out.

We're giving up on this one now, its caused no end of grief since we
moved into the house 3.5 years ago, so we've decided to get a new
boiler instead (WB 30CDi Greenstar). Particularly as we have a new
baby arriving in a matter of days, and the thought of prolonged cold
periods with no heating isn't particularly appealing.

Is this one advantage of a combi? We've had the CH side of it switched
off for months but at least the rest of it has been going strong.

OTOH presumably if the 3 way valve I assume it has inside sticks it isn't
going to be a local plumbers merchant job to fit my own spare...

Not necessarily. You can often free them by removing the actuator and
turning the valve spindle with a pair of pliers.

When I had a Y-Plan system, I used to exercise the CH every day in the
summer in order to heat up the bathroom radiator for an hour to warm the
towels (all other rads turned off). This made the valve much less likely to
seize.

I take it that that carefully chosen minimal edit was a waste of effort
then?

Pretty much. It wasn't big, it wasn't clever and it wasn't funny ;-)

What I (the OP) *meant* was.. a combi will be firing up much more often
than a conventional boiler through the summer, every time a hot tap is
used. The CH valve inside the boiler will be constantly in a hot'n'cold
cycling environment which I would think might make it less likely to
seize? Added to which it's probably a simple two way valve not a three
way.

Anyway ISTR that this boiler cycles all it's valves and stuff briefly
every 19 hours if they haven't been used anyway, so it shouldn't be an
issue...

My conventional probably fires up a couple of times a day in the summer
- certainly at least once - when the hot water temp in the tank drops,
through usage if nothing else.

I've no idea if the valve cycles when it goes on and off HW, but if it
should seize it is out in the open under the bottom shelf in the airing
cupboard, in easy reach of an Engineer's Adjuster. And of course, it
heat cycles when the boiler goes on and off.

And it's running on a closed cycle water system full of Fernox, not raw
mains full of chalk.

So apart from the 19 hours thing, the Combi offers less accessibility,
more complexity, more power and thermal cycles, err... any more
advantages? (oh. The tank.)

...don't forget it's also much more difficult to add a solar preheat stage
to a combi.
