Mira event XS Power Shower problem

[HONDATED]

Does it ever stop I wonder over the last two weeks we have had to buy a new pcb for the boiler and a new washing machine and guess what this morning the shower decided to give up on me so I really need some advice.
The pump in the shower unit is turning but not pumping water.I have checked the solenoid and its got about 3.4 ohms across the terminals and that is as far as I can get with my limited knowledge so can anyone advise me of any further checks I can make before I shell out another £300. All advice would be welcomed thanks.

could be worth checking inlet filters are not blocked, also that isolation valves are open, then next issue could be possible air-locks.

And check the showerhead and pipe are not blocked.

Are you getting any flow ie gravity flow ?
If no flow check filters first.
If getting gravity flow check the impeller they are common to separate from the motor, so the motor may be spinning but impeller isn't.
