More Appliance Repairs

We are no stranger to appliance repairs at TOG. In the past we have taken part in Repair Cafe’s, and we’ve looked at things brought to us by members and visitors. This time it was a Beko DW600 dishwasher that kept burning out its water heater relay every few months. The heater should only be on when heating the water but it seemed to be on all the time, and the machine could be heard gurgling and hissing when filling. On investigation, the Omron G5 relay that powers the water heater had failed with visible burning on the case. The relay failed in the ON state.

This is a very cheap part…. less than 1 Euro. After replacing it several times a few months apart, a bigger and better relay was found after a rummage through our electronics room. A Crydom D2450 solid state relay rated at 45 Amps and zero-crossing switching no less! This should have no trouble handling the approx 7.5A that the heater draws.

What was causing the original relay to fail is not certain. It doesn’t have much air circulation where it is mounted, and the the location of the control PCB itself is very close to the hot inner door of the dishwasher. So time will tell if the new relay can handle the job.

Welder repair

An ancient proverb says that power tool failures occur in threes. During the same week that the lathe motor burned out and the compressor wire meltdown has turned it into a scary noise machine, we also had a mysterious malfunction in one of our welders. It didn’t release any smoke, didn’t make weird noises. It just didn’t weld. 0 volts across the output.

This machine, a small 180A TIG/MMA inverter welder, has recently been repaired. It was not used heavily, as TOG has only so much use for welding. In fact, it was only used by a couple members to practise their welding skills.

On one hand, this machine was 5 year old, has been used extensively in the past and could have been written off as death of old age. The cost of a commercial repair would probably exceed the value of the welder. On the other hand – why not try to repair it ourselves before scrapping it?

TOG at Repair Cafe

repair_smallTOG will be at Sandymount Repair Cafe this coming Saturday (27th) 2pm – 5pm  in Christchurch Hall, Sandymount.

If you have something that is in need of repair and want to know how to do it, drop by on Saturday.

TOG in the Irish Times

TOG was mentioned in the Irish Times on 10th June 2014: No wasters: how to repair a throwaway culture.

Tog, a collaborative makers’ space or “hackerspace” based in an old warehouse on Chancery Lane in Dublin, will help out at the cafe. Tog shares knowledge and tools in everything from 3D printing to knitting. One of its innovations is the Twitter Knitter, whereby Becky Yates, a software engineer, has repurposed a 45-year-old knitting machine to knit tweets.

Next door to Tog is a marketing company, and Tog members love scavenging from its waste. One find was a quantity of rubber ducks, which have been fashioned into a Duck Matrix display. “We’re terrible for puns in this place,” says Tríona O’Connell, part of Tog and a PhD research scientist at Dublin City University.

Ireland’s second Repair Cafe takes place on June 28, at Christchurch Hall, Sandymount, Dublin 4, 2pm-5pm. Some TOG members have previously helped out with the Repair Cafe.

The Twitter Knitter has been shown at Dublin Mini Maker Faire 2013 and at HACK/CHANGE (photos).
