Oh and we check the pressure on the outside tap, that is usually mains supply. Buyapressure gauge from screwfixor toolstation, it's a monument gauge ;-)
Some newbuilds I go to have the washing machine cold water supply coming from the balanced cold, this also causes water hammer. I thought I would give you aheads up incase you encounter more of these issues
Take care

We had to recommend installing a non dynamic valve, a pressure reducing valve that doesn't work on a spring. By installing it after the stop tap on the incoming mains it protects all appliances too.
Hi Burnerman, I just read a post you replied to about fitting a shock arrestor to a washing machine hose. I'm a service engineer and we discovered that we have now gone from water towers to pumping stations so the pressure in some properties went from 1 bar to 7 bar! One guys hot water...
