Hi - I have a creda solarplus cooker (48349) - I wish to replace the 8 bar grill element with a 4 bar grill element - can you please advise me of the steps necessary to do same - yours michael clancy

It’s basically as simple as:

Turn off the gas supply to the range.
Turning off the mains power to the range.
Remove the back panel behind the grill.
Remove the 2 power connectors to the grill element.
Remove the earthing wire to the element screw terminal.
Unscrew the grill element securing screws(s) - there will be 1 or 2 depending on the element fitted to your range.
Refit the new element (make sure it has the same mounting screw holes as the one you want to remove) then secure it.
Reconnect the earthing wire to the element screw post.
Make sure that neither of the element tags touch the chassis - check with a continuity tester of ohm meter and adjust if required.
Reconnect the power cables to the element.
Reconnect the power and check that the element works correctly.
Disconnect the mains power again and replace the rear panel(s).
Reconnect the mains power and recheck that the grill functions correctly.
Turn on the gas supply.
