I Know that there is a concern on the 1200's of the 2005, 2006 models re the servos faiiling. Are there servos on the 1150's as well? And is there anything to look for?
Yep the 1150 is where the ol servo malarky started.( As well as other models) With you in Wandsworth Id be looking for Steptoe. I was told once that the later RT1150's had a slightly better pump unit less prone to failure, whether thats true or not?
