Sebo Dart 1-ET1 Vacuum Not Working/Switch Assembly etc

[jontymox]

Good evening everyone,

I’m wondering if somebody can enlighten me with a problem on the above Sebo upright vacuum cleaner?

Essentially, my customer has dropped off the machine, reporting a “not working” fault, prior to disappearing on holiday at the end of last week!

My customer also confirmed that they had “taken a look themselves,” and removed the switch assembly etc from the handle unit,” leaving it with me to deal with.

I’ve now had a chance to take a look at the above, and the fault appears to be in a broken wire from the flex to handle assembly.

The flex is a two core cable, with what appears to be a rectifier or diode? wire from the on/off switch (live) into the handle loom.

I’ve established that this is the cause of the fault, as when twisting the above wire, the machine powered up.

However, I’m not sure what the above does, and if I can repair it, as it has a well crimped/soldered/heat shrunk joint, or whether it requires further parts…

Could someone advise?

Many thanks,

jonty

cant remember the dart not seen many of them

the sebo X4 has a 2 core input cable but has a heat shrinked component that touches the metal handle. I assume for static build up or the like

can you post some pics of the switch etc

Thank you once again for your help!

I can post some photos of the switch etc, with some difficulty…

You are quite right – the component you mentioned touches the metal handle, and may well be for static build up.

Anyway, the vacuum does power up when twisting the above (broken wire) and I’m trying to ascertain what I need to do to resolve, as I’m not a Sebo/vacuum specialist… perhaps I should try and repair said wire, if possible?

Thanks again,

jonty

can easily get pics of the X4 handle but not sure if it will help, got 3 or 4 round the shop

ps they are really good tough well build vacuum cleaners. I have 2 X4’s at home

this is the x4 handle for reference

this is the Sebo felix which is very similar

Thanks again Dave,

Having taken another look at the above Sebo vacuum, I managed to get it to run very briefly by “twisting the flex” where it enters the handle.

However, I noticed sparking from the above area internally, and quickly disconnected the plug.

Having electrically tested the rocker on/off switch, it is faulty… so I bypassed it ( flex live and neutral to harness into handle live and neutral) and the machine didn’t power up.

I remain perplexed as to the purpose of the rectifier/diode, (or whatever it is!) which is joined to the live wire terminal (to on/ff switch) which then enters the handle…

The above part is broken, so I wonder if it needs to be replaced in order for the machine to work?

no that doide part as you put it is not needed to make it go

its probably a very high ohm resistor so expect 10 megs or so

could be just a faulty switch although flex breaks are the most common

Thanks again Dave,

Yes, it could purely be the faulty on/off switch, although the vacuum did not power up when I bypassed the switch…

[jontymox]

And I’m not entirely sure where the sparking was coming from before… probably the switch, which is definitely faulty, so why didn’t it run when bypassed…

[electrofix]

well all you can do is strip out the motor and check continuity

Just change the cable problem solved

[electrofix]

thought it might be

very common problem but a lovely easy fix
