1979 Hotpoint 1509/10 overhaul

[sesteve]

Well done again. As they say perseverance pays off - apparently and you have certainly persevered with this one.

I'm a bit surprised that it is noisy on the wash as generally the noisiest part is the draining but having said that they all sound slightly different to each other. The noise on my 1509 lessoned quite a bit once I'd sorted out the clutch shoes as one of them had jammed in position and now it makes the same amount of noise for wash and spin.

Is the leak coming from the dreaded support tube? I think that the debor glue that you used to put the counterface in may be causing the problem as it looks from the photos like it could interfere with the movement of the face seal and allow the seals to part when they are moving. Could be worth clearing that out and seeing if that works. Otherwise I think I'm out of suggestions.

Hope you get it sorted

Hi Rob,

I'm glad you stuck with it after all the challenges it has thrown at you. It is a credit to yourself and it looks stunning!

Like me, you have had to strip the 1509 down several times to get it right, I agree with Stephen in saying that the support tube carbon face looks suspect with all that Debor. Try cleaning it up with acetone when you get the time to look at it.

I can imagine your frustration because I would feel the exact same if my 15790 started leaking now but luckily so far so good in my case.

Best of luck!

James

Great

This has been a great thread about a great machine, I still think these are the best machines Hotpoint ever produced.

I too had a few problems with leaks on mine but not to the extent you had with faulty seals, fortunately mine worked but I had a leak after everything else occur on one of the thermostat seals,oh and one of the thermostats stopped working! I remember water testing it just as you did, and the exasperation I felt when there was a drip GRRRRR.....ha ha

But once I had sorted that and everything else what a great machine to use.

I am so pleased you stuck it out and got the beauty up and running

The nightmare ends (for now...)

I have had to tear the machine back down three times, as the small leak escalated grew to a puddle, after every wash.

I took the support tube out, which came originally from the donor machine, which Ian donated to the cause, for which I am very grateful.

To be sure, I took out the counter-face and found a hole in its mounting. Once that was renewed and everything Debored back together, the machine still leaked.

I stripped the machine again and replaced the bottom seal (for the second time) after I found that the carbon face wore some pitting. Back together – still leaking.

I then refaced the rubber seals, took off all Debor sealant and used silicon sealent instead. Back together – the leak had slowed but was still there.

I refitted the original top-hat seal (under the agitator) – the leak persisted. Fitted the old and crusty top-hat seal from the donor machine – no more leaks.

After a boil wash, two 40 degrees washes and a cold wash, not a drop has come down the support tube.

A few weeks ago, the flyback also stopped working – basically the knob had become very stiff to operate. While trying to sort it, the delicate wires from the internal solenoid crumbled. Thankfully, I managed to procure a new flyback, the fitting instructions for which are copied below, in case anyone needs to reference them in the future.

Once again, thanks to everyone that offered advice and even spares to get this old machine running again – it has been quite a journey – one that I hope has now come to an end!

Success

Rob
Congratulations on finally getting everything watertight.

Cheers Ian,
I’ve been using the machine daily, to see how it copes and, so far, not a drop of a leak has come back.

I am tempted to put the back on but that really would tempt fate.

In fact, the machine came into its own yesterday; as we had a huge load of white to get washed (thanks to young Catherine becoming toxic), including bedding, towels, shirts etc. In truth, I think I overloaded it. We put the machine on at 3pm on a 60 degrees wash; the clothes were line dried and back in the house for 7pm, perfectly clean.

With a modern washer, we would have had to use the dryer to get them done in that time…

Well done Rob

Glad you have finally cracked it and I know what you mean about not tempting fate with the back panel but hopefully it can go back on now! Seems like the old seals are better than the new!

Despite being a water guzzler, the quick wash times are a real bonus and the spin is pretty thorough too. I sometimes put mine on late in the evening and use the rinse hold until the morning so I can peg out before I head to work - now that's a test for the seals!

Hi Rob,

Just a quick question regarding your 9605, with the "Rinse Hold" does it agitate for long after releasing the button ?

My aunt had one and my mum had a 1509 but i can't remember the sequence. I have managed to get hold of a brand new 9605W as a back up for my 1504.

Cheers

HI Steve,
Thanks - I had the machine full of water on test for a morning and had no leaks, so I presume that it would stand-up to an overnight rinse-hold. I agree that the spin is pretty effective, although ask me again in the winter.

I need to get some parts to you - a friction damper, a bit of car brake pad and I think I may have a used (but good order) water slinger somewhere. I also found that the cork washer/spring/rubber washer at the top could all be replaced with a sturdy tap washer, if the centre hole was made a little larger. I can send that as well, if you wish.

Hi Keymatic,
I don't know about the 9605 final rinse agitation, as Ian provided me with the machine and it did not work, He would know. On the 1509, it fills with water and just stops, if the rinse hold button is held. When pressed down, it agitates for a few minutes or so (never timed it!)

2 minutes...

...is how long a 96-series top loader will agitate after rinse hold, having already agitated for 1-2 minutes. I've attached the timer chart below for full reference.

I'm fairly sure the 1509 and its ilk agitate for 2 minutes only on the final rinse before pausing for 40 seconds then draining.

 

[sesteve]

Hi Rob

Those parts would be great if you don't mind. Let me know if you want something for postage. I think I gave you my address in one of the emails I sent previously.

Hi Keith. Well done on getting the 9605. Hopefully you won't need it as a backup as the 1504 will keep on going for a long time yet but it's a great backup machine to have. The main difference is the brake being applied after the spins so no coasting which I thought was a bit harsh and also the first agitated rinse along with the brittle console covers of course. I've got a service manual I can send you if you want - it tells you how to disable the agitated fill sequence if this machine has it.

I just checked the manual for the 1509 and the rinse hold kicks in as soon as the machine is full and will agitate for 3 impulses at 40 seconds each so you are right Al 2 mins as well

 

[keymatic]

Hi Rob, thanks for confirming that..it will make life easier if i do decide to use it as currently I have to be around to add the fabric conditioner on the 1504, not really a problem and i have been doing it for over 10yrs now but would be nice to leave the machine with the Rinse Hold option.
It was such a steal at £150 for a brand new 9605 - i think towards the end of manufacturing they were selling for around the £500.
Many thanks for the info
Cheers
Keith

 

[triumphtoledo]

Blimey Keith - yes, £150 is a bargain for a new vertical-type top loader. My renovated 1509 owes me not much less than that...

Steve - I am having a "workshop day" tomorrow, so will try and get together those bits for you - nothing due for the postage - just take it as a big thanks for all your help.

Looks good! So those machines recirculate water for the lint filter on top? Do they use a separate pump?

Dan

 

[triumphtoledo]

Hi Dan...

Yes, the machine recirculates water into the lint tray at the top but it does not utilises a separate pump. Instead, the drain pump rotates in the opposite direction. The drain pump is mechanical and is driven by the main motor by a separate flexible drive (i.e. a piece of canvass!)

Hi Rob,

Yep it was a steal at £150 !! - I think the 1504 has done it's time, what with being in use for well over 10yrs now and never going wrong, plus being over 44 years old.
One question i would throw out to all is can the lid-latch be permanently disengaged ? I know on my aunt's machine i could only open the lid about an inch before the action stopped. On my 1504 it was easy to disable the safety mechanism as it was purely a micro switch, however on the new machine i think its a bit more complicated. As the machine is way outside my collecting timeframe im not over sure on all the technical stuff.

Many Thanks
Keith

Hi Keith

I've attached some info on the lid interlock. The microswitch is located in the lid latch assembly and I guess if you override the microswitch you can use the machine with the lid open as the rest of the interlock is to stop you opening the lid when the gearbox is rotating.

What did you do on your 1504 as is really difficult to defeat it physically whereas the 9506 you just need to stick something in the hole for the lid peg.
