Less than 2yr old SQ FL started giving intermittent NF error code. Repair replaced water valve- one screen was clogged with crystal/grit like material. House is on city water (a recirculting pump put in few years ago for better hot water supply to the far side of house - - where washer is at).
Attaching pix of old water valve. Is this on COLD or HOT water side?
Any ideas/suggestions as to what this is? Bathroom faucet one floor above, on opposite side of house, has similar material aerator screen.
Hard to find plumber/HVAC nowdays as building boom & most prefer working on new builts to a 25 yr old house... i have no experience at all; want to know what type of service i need.
Thanks in advance. I know really not washer issue but so many folks on forum are so knowledgeable!
