Baumatic dishwasher problem?

Hi there,

I have just moved into a rented house and it has a Baumatic dishwasher (not sure of model number as the manual is at home, but I could add this later).

I have never used a dishwasher before, so bought some all in one tabs and my first 2 washes were perfect. When I tried to do my third wash last night, the washer sounded like it was starting for a minute or so, but then stopped and there was just a low humming noise.

The "Add Salt" and "Add Rinse Aid" lights are both lit, but I presumed as I was using all in one tabs that I would not have to add these ? Could this stop a washer from functioning ??

Everything is loaded correctly in the racks, I've cleaned out the filter and can't see anything else wrong.

Sorry for the lack of info, but I've never used a dishwasher before 😜

Any help/info would be greatly appreciated.

Many thanks,
Ade
