Korallia Pump Running In Reverse

[sunnykita]

Hey guys and gals I know this has been discussed before, but I have a korallia pump that since cleaning the motor is running in reverse, it's sucking water through it instead of pushing it out. Does anyone have a fix for this? It's done it before but unplugging it and restarting it has worked in the past. Not this time. Any suggestions would be appreciated.

Little black rubber piece is missing. Its a bumper that forces the prop to spin the other way.

its on the inside of the front cover sheath like jt said is a small little rubber nub if unsure ill take a pic of one of mine but dont worry e-mail hydor and tell them it broke off they will send you new ones lol they did for me without even asking for a receipt and came priority within a week plus is good to have a spare anyway... do you have them on a wave maker?

Thanks JR and Scuba Steve. I will look and see if the rubber piece is there and not aligned correctly or is miswing and will contact. I don't have it on a wave maker.

ya only mentioned the wave maker because if they switch off and start faster than 15 seconds you will guarentee them breaking within 6 months thats why mine are on 30 sec intervals now as per instruction from hydor...... they should insert that to their manuals... if the nub is there i would take off cover and remove the impeller any buildup on the magnet end for some reason will cause it to go in reverse.... prob screws up the strength of the magnetic field not sure but when mine run backwards its allways been one of the two and hydor koralia evo's is all i use for over a year

I had this all the time. Just unplug it and plug it back and keep doing it til it blows out.

just clean the impellers once every 3-4 months and it wont happen at all lol.... took me over a year to figure out how to stop it from happening

Okay, thanks guys. I'love try the plug and unplug routine again and I'll check the magnet too. Thanks again !
