Re: Hoover H130E Washer – Cycle Non-Operation

Replacing the TR1 Power Triac on the Power Module cleared the problem and all is working fine.

I can only assume that current surges (maybe mains surges) and general overheating of the device eventually caused it to fail. The bit of bent aluminium heatsink on the module seems underrated to me.

The Triac is available from RS Components (rswww.com) Stock No. 2512915 and is Part No. BTB12-600BW and cost about £7 with postage. DON’T TRY AND REPLACE THIS UNLESS YOU ARE QUALIFIED IN ELECTRONICS REPAIR.

Thanks to Martin and Pengiun45 for steering me to the cause of the problem. 😉

Thanks for the pointer.

I’m a bit confused 😕 the motor does rotate backwards and forwards (about 1 second each way) but the cycle (any cycle) does not proceed. Does this suggest the motor is okay?

I desoldered TR1 to check it with a Peak semiconductor analyser and found it faulty. I can get the component from RS Components for about £2 and fix this fault. But I wonder will it blow again. Any thoughts?

Replacing the motor and the module may be uneconomic 🙁

TR1 (BTB12 12amp Triac) is blown. TR2 to TR7 Triacs are OK.

Can you shed more light on the likely root cause of TR1 blowing 😕

Hi Martin/Penguin45,

Thanks for the tips.

I have checked the Triacs on the power controller board.

The TR1 (BTB12 12amp Triac) is blown. TR2 thru TR7 low power Triacs are OK.

Can you shed more light on the likely root cause of TR1 blowing.

I didn’t check the water level switch yet. The one with the plastic air tube on it I’m guessing.

Thanks,

Malc C
