This Tuscon is one of the affected ones.

I guess they mean that ones correctly installed and running can be left until replaced. The real problem and one they should have moreso highlighted, are the ones not running.

This is the reply he got.

Friend has now replaced his old Boiler + circ pump so attempted to do a reverse install of the plug, I think it just proves that where there's a will, there's a way because one would really need very large cowboy boots to force the plug on without noticing it, even in the dark or whatever.

Sleeper reported a similar experience with a new one in the suppliers.

Trouble is that once it's flagged as an issue, there's no one going to take the responsibility to say it's safe enough. They couldn't even recommend glueing it in place.

A neighbour has one of these problem pumps. As he has 3 boys under 12 who are always messing about with stuff in the house, he got an electrician in to do a temporary fix until pump is replaced.

The electrician basically got roughly 1.5 metre length of 3 core flex, put a standard 3 pin plug on one end and attached the other end directly to the wiring of the pump. He put a single socket on the wall next to pump and the cable from oil boiler is wired into this socket. Pump is plugged into this socket. It's working OK so far and should be much safer.

Wearb · 19-10-2025 08:54PM

I didn't know you could do that. Is the wiring at the pump side of the pump plug accessible?

I'm not familiar with the set up, just was chatting with my neighbour and he brought up the issue with his pump and described the temporary fix his electrician did in case of accident. As he was away at work when the actual work was done it may have been more complicated than he assumed. But he's happy that's it's working away and much safer now.

Wearb · 19-10-2025 09:14PM

🤨🤨🤨 It would have been nice to know the fix and to scrutinise how satisfactory it is.

While well-intentioned, connecting directly to the pump like this sounds like a possible modification of the product (if done internally) - which in itself may be considered unsafe, even if done by an electrician. I appreciate the situation to begin with is not ideal either though.

John.G · 20-10-2025 06:12AM

Has anyone checked, one, that the pump does not start with plug reversed and, two, check with a multimeter for a voltage or resistance between the pump body and a true earth.

IMHO he should have left it alone until the pump was replaced by the manufacturer.

I am surprised that a electrician would do do something like this, to me it seems like a bodge

PixelCrafter · 20-10-2025 10:14AM

The only temporary safety measure that might make some sense would be to bond the pump with pipework with a very solid connection to ground and ensure it's on an RCD - (Heating system ideally should be anyway and likely is in any reasonably modern installation).

i.e. ground strap on the pump, ground strap on the pipework and make sure it's all properly bonded so any reversal of the plug = instant short and power cut.

Messing with the pump itself isn't a great idea and could void its warranty too.

In a modern installation with RCDs present, this situation really doesn't pose a huge safety risk.

Where it's very risky is in old wiring where the boiler and pumps might just be sitting on a fuse / MCB and particularly where the bonding is not done correctly, as you've a risk of live pipework - and such systems definitely exist out there - you see some very clunky old oil boilers in particular that could be still running on wiring from the 60s/70s.

I know for example in my own installation, when pumps have leaked before, there's been an instant response from the RCBO the heating system sits on.

Whats the story with the recall on these? I've reported it through their site but I've not heard a peep since

PixelCrafter · 20-10-2025 10:26AM

https://www.boards.ie/discussion/comment/123921011#Comment_123921011

Same here - I rang them and they basically said they'd contact me.

It's a huge recall - visiting 100,000 pumps will take a LOT of logistical organisation. Also heating contractors aren't really going to be able to mess around with electrical components, so I would assume they're going to have to change the pumps.

I was a bit annoyed tbh as I had recently had two pumps changed, and had specified Grundos and these were installed instead.

Our system has 4 pumped circuits with non-returns, and they were previously always Grundfos or Wilo. The pumps tended to all have gone after maybe 6-10 years, but the last contractor swapped these in and I'd never heard of the brand.

The oldest ones in the system were Danfoss and lasted decades - don't think Danfoss makes circulator pumps anymore for domestic heating anyway.

I’m not certain, but I have heard the plan is to change the top section including the motor, and that no wet work is anticipated.

Wearb · 20-10-2025 09:07PM

Good luck to them with that. A lot of isolation valves fail when disturbed.

Hopefully they won't ask the customer to foot the bill for that, by claiming that those valves have nothing to do with their pump problem.

Exactly, that was horse manure from that poster. Tanks rarely exceed 80C and cannot exceed 100C, naturally. The melt point, let alone autoignition temperature of very few materials is under 100C

As others have mentioned, it's the symmetrical nature of the connector is the real issue.

https://www.boards.ie/discussion/comment/123923014#Comment_123923014

I gather the plan is that they won’t need to isolate, the top section including the motor can supposedly be replaced without any release of water.

The impellar (which is obviously in the water stream) is -necessarily- stuck on the shaft of the motor and comes off with the motor.

It's strange that there's not been reports of changeouts already.

They might have insurance problems getting coverage for the recall which will not be cheap.

Maybe they have some way of separating the motor and pump shaft? I haven’t seen it, so really have no idea - but one of their staff mentioned to me that the solution involved replacing the motor.
