Shower starts hot then runs cold?

I have an aquatronic W7000 shower. Recently it has started to run cold after about 30 seconds of use, remaining cold for about 30 secs then runs hot again. Is this a problem I can fix or do I need a new shower? Any help much appreciated.

this could have been the inlet filter blocked with various sludge, especially in a hard water area. take unit off and clean filter.

For anyone interested the heating element had gone on the shower which apparantly is more expensive to replace than buy a new shower. Happy now with a Triton Jade installed.

Not an expert but it could be simply due to insufficient water pressure. Have you tried contacting the manufacturer?
