Just installed a triton t300si shower and low pressure light is on.Plumber insists that water pressure is OK but inlet filter is clean and hose is clear.When started start button flashes and water spurts do I need a new pcb?

Hi PS1...

We don't work on POWER SHOWERS here in the USA... not yet anyway!

I would advise you to contact the manufacturer of the triton shower system and see what they think here. CLick on this link for more info... contact the TECHNICAL SUPPORT DEPARTMENT:

Triton Showers - Electric Showers, Mixer Showers, Power Showers, Digital Showers, Bathroom Accessories

I would also tell the plumber that installed this that he needs to help you resolve this as you expected a working shower to be installed... not excuses! I would even suggest that you hold the final payment until this is resolved... that should help to get him involved a bit quicker!

Good luck!
