Vailant Aqua Plus Hot Water Flow Issues Please Help

[jkarrows]

OK my boiler on central heating is fine but on the hot water supply its got very low water flow and pressure, its hot but the amount were getting out is slow and low pressure.

I have checked the incoming water flow and pressure and thats fine, more then the boiler needs as it was checked by the water board and its around 42 litres a minute and around 2.25psi.

The DHW pump has been changed and still its no good, anyone advise please?

Just a thought do u have the warmstart turned on this is what charges the tank and hence operates the pump on this model??

Is there a filter/strainer on AquaPLUS?

Also, I believe there's a non return valve in there.

Either could get partially blocked in time.
