Sorry to hear of problems with your T70si Shower unit.
On the basis that there is no interruption to the power or water supply to the shower I would recomend giving our Customer Service Dept a call, they should be able to assist further for you and may be contacted by telephone on 0844 980 0750.
Best Regards,
