Diplex Quantum heating element vibrations

[Boldee]

I hope someone can point me in the right direction here, I have a Diplex Quantum 150rf that was installed 18 month's ago, I turned it off over the summer and now its getting cooler I have turned it back on and now it appears that the bottom heating element is vibrating when its charging.

This happens at the start of charging for approximately the first hour and then it slowly stops, I assume this is due to expansion, all the noise comes from the right hand side where all the connections are, despite the noise it works just fine.

Any suggestions how best to stop these vibrations?

Have you called Dimplex technical support ?

Emailed them but still waiting for a reply, I thought I would ask here in case anyone else had this problem.
