We've put T back into disposable nappies for the duration. A good friend has taken the washing we had and done it for us - including three days worth of nappies.
Given the age of the machine DH figured he might as well investigate what had gone wrong and whether he could repair it. Turns out that the motor brushes had worn out. DH tried to go on-line to get spares over the weekend but the manufacturer's website has some broken code which meant it wouldn't list parts! DH has rung them this morning and the spares are available at a cost of only £20. But.... they are out of stock and will be about three weeks!
Ho hum. I guess at least the spares are available and they manufacturer didn't just say it was too old and we have to replace the machine!
