Hotpoint DWF33 drawing 4.5kw at mid cycle

[dangerousdave2]

With energy consumption rising rapidly, I borrowed an instant read power use meter and started checking the household appliances.
The Hotpoint Aquarius DWF33 dishwasher was drawing 4.5kw. I dont know for how long or at what point in the cycle. However, this seems excessive. Will a damaged heating element cause this?
The machine works well otherwise and is very quiet.

Thank you for your ideas…

Doesn’t sound right, thats 18 amps and it has a 13 amp fuse, shouldn’t the fuse have blown then.
Element in any dishwasher is normally no more that 2KW.

It doesnt trip the fuse, or blow fuses in the plug.
The meter is attached to the mains supply, with a remote digital read out.

It was reading 5.554 kw which is huge. The highest it was before was 3.1 kw with a 30+ year old oil filled radiator on. (That is going to be banished to the recycling centre.)

When I turned the dishwasher off the reading was 0.9.. something!
So, if it was 0.999, say 1 kw, then the dishwasher was drawing 4.554 kw.

I did this three times and each time it went from 0.9.. to 5.554 and back again.

I think 13 amp fuses blow instantly at about 20 amps and at about 15 continuous… but that is just an ill informed memory i have somewhere.

The dishwasher was drawing at least 4.5kw. For how long and why, I dont know.
