A job well done Lee.
as Gary mentions, matching the paint would have been difficult.
Rust repair was the aim and you have succeeded in that, by the looks of it.
The door will hide that lip of white paint anyway - the preservation of the machine is the aim.
Re the Economy stuff - taken from Hotpoints Product Information brochure for the 18580/18680:
'11.Sales feature ........... E button allows programmes 1,
2 or 3 to wash at the temperature of the incoming
hot water (or 40 degrees whichever is the higher)
Customer benefit.........saves electricity and time on very hot washes'
than later in the brochure:
ECONOMY BUTTON (Programmes 1, 2 or 3)
When button is depressed, allows the timer to index on instead of pausing for heating up period if hot water is abover 40*c. Press the button again to release.
Hope that explains it.
Keep up the good work Lee - wonderful that such a great condition 18680 is in safe hands.
what luck you had stumbling across that one!
cheers
