    Worcester 30cdi loud rumble after hot tap turned off

    Hi. Our Worcester 30cdi makes a very loud rumbling noise after the hot tap is turned off. It seems to be worse if the hot tap is only run for a short time. The noise is getting worse since this video was done. Any advice gratefully received.
