Tile moving, underfloor heating cable underneath...What to do?

[maximus16]

Hi everyone!3 months ago I've tiled my kitchen with an underfloor heating cable underneath( originally it was a bitumen floor, what I've done: I've laid a insulation floor boards using a flexible tile glue installed heating cables and and laid my tiles straight on the top ) everything went o.k, until I've noticed that couple of tiles moving(grout coming off).Don' know what to do. Looks like another massive job:smash:
many thanks!

Loads more onfo required, What tiles, adhesive and grout. How long before ufh was turned on

Polished porcelain floor tiles, evo-stik flexible tile adhesive, ultra flexjoint grout. Ufh wasn't on at least a week after installation. 🙁

If its only a couple of tiles moving,try lifting them out without breaking them,if not use new tiles,Clean the old addy off the floor,being careful with the UFH wires,check the floor is solid then simply refix the tiles and re-grout

Is there a special primer i can use before I stick them back?

just another silly question mate,but you DID have good coverage on the rear of the tiles didnt you?
