if water goes into tray high up your pumps prob gone, at rear grey chamber two pipes come out of it. theres a float sw and pump in there. water collects and wont pump up to bottle. if tray/bottle low down foot level prob resevoir chamber blocked. everything needs to come out fot that. think itll be 1st type with draw/bottle high up so look at rear. prise away at top . plastic may snap becareful but if does dont panic
