New leak on 9-yr old HansGrohe shower valve

I just removed my shower valve cartridge assembly to clean (we had low water flow), the left side input screen (it was clogged with scale particles). I reinstalled the white plastic screen retainer (one one either side of the valve mechanism). I dabbed a little silicon grease on the o-rings and reinstalled the four screws. Turned the water back on to the house and got a cup of coffee. When I returned to the bathroom, water was dripping out of the hand held shower (shower fixture only--no tub). Turned off main again and removed the cartridge assembly thinking an o-ring pinched/split/fell off. Both were on the unit and the small dab of grease was smeared. The valve assembly has be in use for 9-years without a problem and this was the first time I've removed it since it was installed. Should I install new o-rings or could the valve assembly be my first step? Thanks...
