'ise,
I can't say that I'm that ken on the replace everything theory.
We had a Washing machine "Technician" at work a few years back, that used to get all sorts of complaints, about the cost of the jobs he done.
It turned out that he would replace various parts of the W/M until it worked properly, piece by piece, he was fired after he replaced ALL of the parts in a 2 month old W/Machine that had a faulty power cord, this must have been the last part that he replaced and charged the customer NZ$700 + Labour!.
Even so, the thing was still under warranty,
servicing by trial and error is just not my style. [Linked Image]
Good riddance to bad rubbish, eh?.
