hoover T5090 twintub

Hi everyone
I have always wondered why this machine will pump water with the force of a jet washer when spin drying but when emptying the wash tub there's just a slow lazy trickle .I have looked at the pump but cant find anything wrong and there are no blockages anywhere .Is there anything i can do to improve the flow .My mum bought her first Hoovermatic in 1959 when i was just a baby and over the following years as one machine wore out she would get the latest model the 5090 being the last .PS i have two of these machines the other one has the same fault [if it is a fault] regards Tony

HI Anthony, Is your model the same one that was manufactured here in the USA? I just used mine today and the tub does drain slowly. When it spins, the water really rushes out and when you drain the main tub, the water drains slowly. Thanks, Gary

Hi Anthony,

When inspecting the pump, did the rubber caps on the valve seat firmly against one of the entries in both positions?

It's likely that the pump is sucking in air from the spinner and this slows things down considerably. It's a very common fault on most used Hoovermatics.

Pumps on Hoovermatics

We not their strongest point, at least the early models from what one can see. Perhaps when they went over to plastic tubs things were different.

There is a reason why those Hoover pumps come apart, sooner or later you'll need to repair or replace certain valves or other parts. *LOL*

As already stated the valve that closes off the port between spinner and wash tub sometimes (or often depending upon how much the machine is used) weakens and or otherwise does not form a tight seal. Once that happens you will get air or water (depending on what is in the spin tub) leaking over when you are trying to drain the wash tub.

Easy way to see what is going on is to take off the back of unit. Then fill wash tub with water then set controls to "drain" and observe the pump. If you start seeing water leading from the top of pump (where the metal rod hooks into) the valves are starting to go.

The valves also can dry out and weaken if the machine is left idle too long. Also heavy residue of soap/detergent and or hard water scum that is left to dry can eventually gum up the pump.

the pump

is a new one when I say new it came from my old van stock so its probably about 30 years old .Its been on this machine for about a year I have had it open and its still nice and clean inside but I will open it again just to check that the valves are opening and closing correctly . I have two more new pumps still in there wrappers so could just fit a new one but I know they are scarce now so I would like to fix the old one if possible .I originally took the machine apart because the spinner was making a terrible screeching sound . After. slapping some grease on its bearings its now screech free .

Pump on my Hoover TT was NIB as well.

When installed years ago now, but the thing does leak from the diverter valve at times. Do not use the thing that often (if once a year that would be saying something) so that could be causing problems.

Thing is just don't have the patience and or stamina often to deal with the Hoover. Swear a posser, tub and mangle is faster.

Hi Anthony

well I don't think it is a fault, but an intentional part of the pump design.

when you look at the holes into the valve chamber, the hole from the washtub is smaller than that from the spinner even though the hose connections are the same size. I suspect this is to slow the flow of water into the pump from the washtub, so to reduce the load on the pump and therefore the motor. Notice when you empty the tub how the spinner motor picks up speed when the last of the water drains away. Whereas the spin dryer doesn't fill with any substantial head of water when compared to the washtub and there for wouldn't have the pressure of water forcing it's way into the pump. I don't have a degree in fluid dynamics, but I suspect the more water that flows through a pump in a given time the more energy it uses, so would make sense to me to reduce the water flowing into the pump down to a level the motor and belt can supply.

That said, years ago I did drill out the hole on washtub side of the valve chamber and it pumped out at a fantastic rate, though I can't remember if it seemed to strain the motor any more than normal, but I know it didn't harm the motor, at least not in the short time I had the machine for.

thanks Keymatic

after almost 40 years of repairing Hoover appliances I had never noticed that hole being smaller and I know exactly what you mean about the motor slowing down when spinning clothes but only till the bulk of the water has been shifted .I am going to enlarge the hole but only a fraction just to see what improvement I get .The motor is more than capable of taking the strain if it can spin a can full of soaking wet clothes and run the pump at the same time it should be fine and the quicker it drains the wash tub the sooner it is switched off thanks again for pointing that out I will let you know how I get on

 

[anthony]

deed done

well guys I went ahead and enlarged the hole but not to much [just took a shade off with the Dremmel ]and I have to say the results are fantastic not only will the machine empty in less than 2 mins its a lot quieter no longer can you hear the spindryer screaming away needless to say I am delighted .Here's a tip for those of you with pumps leaking from the valve post on the top .Remove the clip and the washer and slap on a 1/2 inch tap washer smothered in grease put the washer and the clip back on and that should cure it .I have done lots of them over the years and 9 times out of 10 it works. Another tip for making the machine quieter is to squirt some of that expanding foam up between the wash tub and the outer casing it absorbs a lot of the vibration when spinning

I wish this fix would work for my 0519, but because it uses a different pump, the drain line to the spinner is open all the time, and the wash tub drain line is controlled by a pinch valve. This causes the pump to mix in air from the spin tub when it is empty and you are trying to drain the wash tub, which produces a noticeable difference in water flow/pressure between pumping from the spin tub and pumping out the wash tub. Next time I have my machine out, I'm going to time how long it takes to empty the tub, and then using a pair of locking pliers pinch off the drain line coming from the spinner and time the wash tub drain again... I'm guessing it will be much faster.

I've done exactly the same as you, with the tap washers and some silicone grease. though not tried the insulation foam.

I assume the spinner doesn't scream whilst emptying as it's going slightly slower due to a greater load on the pump, does the spinner speed up more noticeably at the point the tub is empty? But as you say the spin motors are quite powerful enough, and lets face it we must all have a few spares tucked away should the worst happen. I couldn't tell you how many wash tub motors I have and has anyone ever come across one burnt out?, yet I have to keep them just in case lol.

[anthony]

yes i know what you mean

I have tons of spares and I to have yet to see a burnt out motor. the spinner speeds up once the water has gone just like it does when spinning clothes.Its also amusing to see how these Hoovermatics became flimsier as the models progressed [and got more expensive .I think my mums first one bought in 1959 cost about 65 quid the 5090 I have cost around 400
