Dessalator Duo100 220V motor problem

My Dessalator has stopped working on the 220V setting. When I turn it on all I get is a humming sound, I think from the control unit. The motor does not turn.

However on the 12V motor setting it still runs ok. So maybe the 220v motor has failed? Anyone had a problem like this or any ideas, please?

Thanks
Dave

Re: Dessalator Duo100 220V motor problem

Did you try to call/email Dessalator ? I had good support from when I installed mine last year. But you have plenty of solar so why don't you just trash that 230V motor and save a few kg ?

Before anything else, grab your voltmeter and check that power is reaching the motor. Could be a fuse or corroded cables for instance.

Re: Dessalator Duo100 220V motor problem

Dave, on a few occasions now we have had to clean up all the cable connections of oxidation. Check these.

Also, there is a grey cable that runs from the DC motorís small electrical box to behind the control panel. This provides millliamps the components here. Make sure that these connections, on both ends, are also very clean. This one has been a source of our issues a few times.

Re: Dessalator Duo100 220V motor problem

Thanks everyone for your replies. The people at Dessalator got straight back to me with a person to contact. It was a phone number so with different time zones I have asked for email information.

Thanks Steve, I will have a look at all the connections. At least the unit works with the 12V system. However the problem with using the 12V is it draws the full 50A from the battery system and the charger doesn't quite keep up, so I get a discharge.

Re: Dessalator Duo100 220V motor problem

Same happened to ours. The capacitor on the AC motor had failed. It had a bulge in it. Bought replacement + spare from Dessalator agent in USA for $27ea- the markings on it are:


Brand Comar Condensatori - made in in italy
MKA 30 - 450
uF 30 +-5%
Un 400 Vac B
Un 450 Vac C
25/85/21 PO 50Hz
05/23/03

Take a photo of the old one's wiring before disassembly.

Re: Dessalator Duo100 220V motor problem

Make sure capacitor is discharged first before touching its connectors.

There are U tubes on doing this.

Yes, good idea .

Dessalator have suggested the same thing, to replace the capacitor. 30 micro farad.

Re: Dessalator Duo100 220V motor problem

Dear Dave, I had the same problem and got it resolved by changing the accumulator that is on the motor (To ease start mode) a 4.5 inch long, 1.5 inch diameter white Bobin... Good luck, and whatever others say, having the flex to operate both 220V and 12 V systems is a definite +. Just don't forget to work the 12V once on a while as the motor and fan bearings get dry quickly! Spray 100 per cent silicone at both ends... Good luck!

Re: Dessalator Duo100 220V motor problem

Ive changed our capacitor 3 times now, each with blown out sides. Ive easily found these in electrical hobby type shops for $10-ish. 30uF as it was suggested by Dessalator to step it up from 25uF.
Keep a few spares of these

Dave, did you find the reason for your DC stoppage?

Re: Dessalator Duo100 220V motor problem

Hi Steve, thanks for the info. How did you discharge your capacitor?

DC stoppage? Nope just the 220v AC problem.
