Whirlpool Bath tripping RCD

[Trouble666]

Hi Guys,

Recently I have had a new bathroom in which I have had a shower, extractor fan and (phoenix) whirlpool bath installed;

The electrician connected them upto an independent RCD but as of late, the whirlpool is tripping the RCD.

Any ideas why this may be? Admittedly, I haven't removed the panel yet to check for water ingress, but is there anything obvious that might be causing this?


Thanks for your help!

I think that is the obvious answer.
