My wife pressed the start button on the Dualit Milk Frother (Model DMF2) one day in the summer of 2017 and it no longer worked. This persisted so we had to heat the milk in the microwave oven for a week or two until we got a new frother.
Of course, me being me, I dismantled the faulty Dualit Milk Frother to see if there was an obvious problem. There wasn’t anything burnt out or blackened. Just a lot of wiring in a very confined space. It was constructed with a flat straight circuit board fitted into a curved space. No-one had used flexible circuit boards here.
The long term solution was to replace the whole Dualit Milk Frother. Since they are still on the market that’s what I chose to do. The faulty one had been a replacement for our Nespresso Aeroccino Milk Frother already mentioned in this blog. We now had to replace the replacement.
