What to do when the water pump in your Tuttnauer autoclave is not pumping water
It may sound silly to offer advice on what you can do when the water pump on your Tuttnauer autoclave is not pumping water. You just replace it, right? Who has time to worry about what could really be causing the problem? The pump doesn’t work, you call the repairman and tell him to fix it.
But if you’ve ever sent your autoclave in for any kind of repair, then you know how expensive it can be. He not only has to pay for parts and labor, but he’ll also have to pay for shipping and handling, both ways! And let’s not forget: he’ll also need to rent a machine to help him out for the next 4-6 weeks. After he’s finished shelling out all that money, he could almost buy a new machine!
So don’t be too quick to consign that poor water pump to the landfill. It can be a simple problem that will only take a minute or two to fix. And if you find the problem and fix it yourself, you’ll save yourself a ton of money and hassle. Here’s what you can do if your Tuttnauer water pump isn’t pumping water like it’s supposed to.
Check pump filter. It may just be clogged. Clean it up and use the water inlet key to run the pump. If it works, problem solved! See how easy was that?
If it doesn’t work, you’ll need to check the fill solenoid. Do not panic. It is easy.
Use something made of steel, like a screwdriver, and place it on the center post of the fill solenoid to see if the magnetic field activates. If so, that means the solenoid has been activated.
If you do not detect a magnetic field, listen for a small ‘click’ when you turn the pump on. That ‘click’ sound means the solenoid should be open.
If you do not hear the click, open the solenoid valve, remove the plunger, and replace the housing. Now use the water inlet key to run the pump. If water now gets into the chamber then the problem was the plunger and you will need to replace it.
Now, if there is still no water, remove the casing again and press the water inlet key again. If you see water coming through the valve base, the problem is a blockage or crimp in the tubing that runs from the valve base to the bladder.
However, if you do not see water at the base of the valve, then the problem is with the pump and you will need to replace it.
As you can see, if your Tuttnauer water pump isn’t pumping water, it’s a pretty easy fix. And even if you have to replace it, you’ve already seen how easy it is to make all the necessary connections. You will save a lot of money if you repair it yourself.
