Re: Error code135
Never come across your error code as stated.
However your best bet is to first have a look and check out the motor brushes before doing anything else presuming that the machine pumps out, the air chamber is not blocked up ( trace the thin black hose from the pressure switch down to the sump hose and ye shall find it ).
If you find the m/brushes are worn out and have a multimeter check each brush tag to its terminal block for a reading – continuity = a buzz on most meters that way you prove that the internal winding fuse has not blown. If the commutator looks a trite iffy with a tiny ridge in the middle get some very very fine sand paper and gently turn the spindle ( armature ) and lightly apply a bit of thumb pressure on the s/paper to dress it up. If it all looks somewhat suspect buy a set of the cheap 4 quid motor brushes to try rather than lashing out 30 quid or so on a superior genuine pair, all you want to initially prove is that the motor works.
You may well need to do the reset again afterwards.
You do not give the ENR model number ( behing the door on label at top ). If proved motor zapped there are some CE-SET Qualtex ( which seem to be to date ok ) after market motors for about 70/80 quid rather than Bosches rather fanciful 200 odd quid motors but you`d have to check it these motors are comparable first.
All the best.
