How to reset clock on stoves 900g oven - Stoves Premier 900GRa Gas Double Oven

SOURCE: Stoves 900G gas oven stopped working

A lot of times the problem is with a dirty or a clogged burner. Make sure the burner is clean.
If you have a pilotless model, it uses a spark igniter to ignite the gas, which works in a combination with a spark switch (located on the burner gas valve) and a spark module. Because it is not simple to test these parts and find out which one is defective, we recommend to contact a professional appliance technician.

does anyone know were i can get a replacement top oven inner glass for my stoves heritage 720EF ?

SOURCE: I have a stoves 720ef anf for no obvious reason the clock resets to 23.59 and the oven turns off, can you suggest anything

You obviously have a power loss somewhere. The oven will not work unless a time is set on the clock. I would suggest you have problem with the feed to the cooker which an electician should be able to check it out. If anything else is wrong on the cooker, it shouldn't reset the clock.
