Hi. My autoclave door won't open because chamber pressure is too low. What should I do?

Technical Manual and other suggestions. Professional machines really need professional service as the repair is very specialized, and the dangers of using incorrectly sterilized tools injurious to health.

Check the drain pipe that vents steam through resevoir at end of cycle , could be simple debris blockage, or vent valve not opening,play safe autoclaves are like accidents waiting for a place to happen -steam under pressure..

It should be seen by a tech, because he must open the esterilizer to unblock the door and replace the gasket.

Error 3 is a Door lock error and has nothing to do with the water sensor. Tighten the door down snuggly, but don't over-tighten. If it still doesn't work it may need a door rebuild or switch replacement. Call for service if it doesn't restart.

need to clean your screens and filters.. also clean out your chamber and pay attention to the sensors there...

The E13 error code on an Enigma 8 autoclave typically indicates a problem with the vacuum system. This error code is indicating that the vacuum is not reaching the proper level during the sterilization cycle.
Here are a few things you can check to fix the E13 error code:

1. Check the vacuum pump: Make sure that the vacuum pump is functioning properly and that it is not blocked or clogged.
2. Check the air filter: Make sure that the air filter is clean and not clogged. A clogged air filter can prevent the vacuum pump from functioning properly.
3. Check the vacuum hose: Make sure that the vacuum hose is not damaged or disconnected.
4. Check the door gasket: Make sure that the door gasket is not damaged or leaking. A damaged or leaking door gasket can prevent the vacuum from reaching the proper level.
5. Check the control board: Make sure that the control board is not damaged or malfunctioning.
6. Check the water level: Make sure that the water level is at the correct level in the autoclave chamber.

Check the rubber door (safety locking device) bellows. If it is cracked it will leak

Oh no, you have bought a "Runyes" Chinese unit. "Run - Yes" is the best option. Sell it & buy something better.
But, E4 is to do with Temp or Pressure not right.
"

Code E4:constant temperature and constant pressure failed.

(the chamber pressure tolerance is greater than 0.25bar or temperature tolerance greater than 2.5?)

Solution:

A. please check if you can open the solenoid valve which the steam gets into.

B. please refer to E2 process
---------------------
For E2 try:

Code E2:Chamber overpressure

(The chamber pressure is above 2.4 bar for longer than 2 seconds)

Solution:

A. Please check when the pressure rises, the chamber inner temperature will also rise up. If not or rise up very slowly, then you should check the inner temperature sensor, please refer to E1-C1 process.

B. The chamber keep vacuum pressure, the vacuum pressure will be -0.7 bar within 4 minutes under normally room temperature, and it will above 0.1 bar within 5 minutes if the pressure do not leak out, otherwise, you should check the chamber cover, solenoid valve, safety valve, vacuum pump, connector welded points, till you find the problems where and why the pressure leak out, then solve the problems if you find it.

C. During the machine normally working cycle, please observe if the machine vacuum could be lower than -0.6 bar, even lower than -0.7 bar if the machine is still cold.

D. Adjust the chamber cover and tighten a little if necessary.

E. When you run a cycle for the first time with a packed or non packed instruments and it comes up with E2, please don't worry. It will not come out with the E2 alarm again when you run it the second time.

Hi,
Never reach inside the washing machine with it connected to the mains. The door interlock is always live.
There are several reasons why a Hotpoint door could be jammed shut.
•A broken door catch or door frame where the door catch screws in (they are rubbish on many Hotpoints - always breaking) you can sometimes get the door open if you push the door firmly in as you open it
•If there is water still inside the washing machine, then the door wont open either on these Hotpoint washing machines (not on some others though) If this is the case, when you try to open the door the ****** won't try to move down at all. You can open the door usually if you drain the machine. (only applicable with door interlocks that have a rubber pressure hose attached to them)
•A faulty door interlock
•The pressure chamber can be blocked on some earlier Hotpoint washing machines which gives the same effect as having water in the machine. Basically the washer "thinks" there is water in when there isn't. This would require the washing machine being stripped down to remove and clean the pressure chamber bottle. This cause is only applicable to washing machines where a small rubber hose is connected to the door interlock. This hose allows the door mechanism to be locked and unlocked by air pressure activated by water rising inside the pressure chamber bottle attached at the other end on the tub. Gunge can block the very small aperture where the pressure hose fits to the pressure chamber bottle.
