Numatic's latest line of Henry and Hetty machines with the 'Eco save' seem to be suffering from premature failure due to an issue with the circuitry for the eco control.
I was just wondering if anybody else has noticed this?
What happens is the machine just stops working. It won't turn on, although most of the time the red light for the power boost will light up when power is supplied.
The first time I came across this I suspected it was worn carbon brushes.
I've repaired two of these machines recently for friends, both Hetty's coincidentally.
To minimise cost and eradicate the risk of future failure what I do is remove the eco system from the machine. This means ripping all the wiring out for it, the circuit board and disconnecting the 'Boost' button. This leaves you with a machine similar to the very early Herny. You flick the power button and the machine instantly runs on full power. The Eco button is now dead and does nothing as it's not connected to anything.
The owners of the machines I've repaired so far have been happy with this as they always used the machine on full power anyway, so this saves them having to press the boost button every time the machine is used.
I've seen quite a few machines on eBay too listed as 'spares or repairs' with exactly the same symptoms listed.
Has anybody else come across this issue at all?
It seems a shame that there is a risk of Numatic's superb reliability record being tarnished somewhat by a few wayward circuit boards... I wonder if they'd be better doing away with the 'Eco' gimmick and reverting back to the setup with a rocker on/off switch and a manual rocker switch with high and low options?
