My washing machine is too heavy for me to move (alternatively, I am a
nine stone weakling). It is not level. The problem seems to be at
the back. Are the rear feet adjustable or just the ones at the front?

The problem is it that the contractors between the lot of them - and
blaming each other - omitted to level the floor. Rather than spend
time arguing on the phone, I would prefer to get an idea of what is
needed so I can just get a mate to help me fix the problem for a
curry.

(Yes, this is the same utility room with the Schuko socket and
questionable method of installation, now resolved.)
