If the original filter housing is OK, then a standard Askoll will fit directly. You may have to cut the plug off and retag the wires if it’s a 2 tag generic PMP988 say. The Zanussi type Askoll with the round mounting face and 2 wire block plug socket can also be used.
Probably, but saying as there’s no gtee doesn’t really matter! 90 mile round trip to fix it,still haven’t decided who’s paying, I could do without the hassle at the moment. Might just bite the bullet and take the cost,and tell them I won’t repair it again
