Plug in timer "not suitable for washing machines"?!
I have a digital plug in timer which says on the back, "Not suitable for dishwashers and washing machines". The only reason I can think of is the inductance of the motor. But it's rated at 3.2kW, and it uses a relay (I can hear it). So why?

Well most machines these days seem to use their own delay timers and need to
be powered to keep the machine in the mode you set it to on the menu. If its an old mechanical one then I'd have no issues, but of course with cold fill the heater is often quite a high current.

The timer is rated at 3.2kW, so it's not the current that's the problem.
If the washing machine had a delay timer, you wouldn't be trying to use the plugin timer anyway. My washing machine requires me to press start to turn it on. I haven't tried it, but I don't know if it would work if I pressed start, then shut off the mains, then put it back on later. It would be a bit clumsy though, you'd have to give the machine power while you started it, then put it on the timer. Not sure why you'd put a washing machine on timer anyway, I just put it on when I have a load of washing to do. Timers are for things like lights or heaters.

If you were on an Economy 7 tariff you would think differently! Most recent machines require mains supply to hold the settings until you press the start button - or the onboard timer selects start. I guess the timer manufacturer is warning of this likelyhood to avoid complaints. |

Yeah it is, I've got this special high tech timer called an alarm clock that's set to go off when I have to start a wash/dryer cycle. I can live with getting up in the middle of the night for an hour once a week. I'm really tough. :) |

But it's rated at 3.2kW, and it uses a relay (I can hear it). So why? It may be rated for the motor current if its that. |

Some do handle what they think it's a short term mains failure gracefully by just carrying on regardless when the mains comes back, but those are usually the better designed ones which will almost certainly have a delayed start function so you can get it to use the power when its cheapest. It would be a bit clumsy though, you'd have to give the machine power while you started it, then put it on the timer. Yeah, it would be much more convenient to get a better designed machine. Not sure why you'd put a washing machine on timer anyway, Because some get cheaper electricity at some times of the day. I just put it on when I have a load of washing to do. I do too, but the electricity costs the same regardless of when I use it and I wash in cold water anyway so the amount of power it uses isn't very high at all, not enough to bother about even if I was on a time of use tariff. Timers are for things like lights or heaters. And for higher power devices like washing machines and dishwashers when on a time of use tariff.

I guess the timer manufacturer is warning of this likelyhood to avoid complaints. I've a John Lewis own-brand (basically AEG) and if I put in all the settings, including delay timer, then switch off at the socket it holds all of the settings. If I use the switch on the machine the programme reverts to Cotton 60. I've never tried starting it first then switching off at the socket and back on - must do so some time. I still have a box with an electromechanical time and 13A socket that was built for a GF's machine about 30-odd years ago. -- Peter. The gods will stay away whilst religions hold sway |
