6100's stopped working...

[gazpep]

Sorry if this is a little long Roger.

I had the notorious squealing alarm go off and noticed that both 6100's stopped working. I've had them for about 15 months and they have never had any maintenance so after searching the forum I knew that cleaning would probably solve the problem and sure enough after soaking both streams in vinegar overnight they both returned to normal operation.......

....anyway as soon as I had the streams working again I decided that I should do a bit of tank cleaning and in the process somehow managed to dislodge the tube that feeds water from the top of the tank and into the Calcium reactor and before I knew it the household earth leakage device had shut the power off...to cut a long story short I saw that some water had entered one of the power boards ( not the one that powers the streams). Anyway, after the power was restored I discovered that the streams no longer worked and I had a close look at where the driver boxes are mounted and saw a few drips of water in their vicinity. I can't say for sure but I'm worried that water may have gotten into one or both of the boxes.

The multicontroller and the two transformers are all well away from the area that had the water dripping so I'm sure that none of them got wet.

The streams each have their own switch on the same power board which is also well away from where the water dripped.

These are the symptoms; I switch the LH side stream on and nothing happens - none of the LED's on the multicontroller lights up and neither stream works. I switch the RH side one on and the red (power) LED and the four lower yellow LEDS on the mulicontroller light up and after a few seconds the driver/s (I can't tell if it's one or both ?) start to squeal and neither stream works..... I switch the RH one off and the sqealing stops -and the LED's go out. Once again neither of the streams work.

I'm puzzled as to why if one of the driver boxes got wet then why would both streams and the muticontroller be affected ?. If both had gotten wet then why do they react differently viz a viz the multicontroller.....


Any ideas would be appreciated.

the streams power the controller via the din cables as such you need to test the streams on their own to see if they work.

So disconnect them from the 7094 or 7095 and just check if they run if not then you need to find out why. I would not try to run them on the controller until you are sure the pumps are ok.

It also depends what parts got wet, it is possible to get them wet in such a way they still power the controller but once they are wet they are generally toast and have to be replaced.

Just an update on this.


I tried switching drivers around, unplugging the multicontroller etc....still no sign of life from either of the streams.

Anyway, I thought I'd try something that has worked for me in the past on old Eheim pumps that had stalled....I got a long metal skewer from the kitchen and with the streams switched on (and squealing) I used the skewer to turn the propellors..... bingo... both streams then instantly started...

The thing that still has me puzzled though is why they were both working fine after being soaked in vinegar then wouldn't start again after the power had been restored following the water leakage incident which had cut the power....the fact that both pumps simultaneously refused to re-start is a mystery to me...

It sounds to me like the drive units are still dirty or have excess wear. Please double check the stickied thread at the top of the forum paying attention to the upper bearing and the hole in the center of the magnet.
