3. Check if the pump is working; if not, replace the pump.
4. Check if the positive-pressure sensor and the corresponding electrical circuit are in normal
working order. First replace a reagent testing panel and reconnect its tubing, then check if the
positive pressure is normal in the status interface; if it is normal after the replacement, this means
that the positive-pressure sensor and the corresponding electrical circuit are causing a problem
with building positive pressure (After the reagent testing panel is replaced, note that the tubing
needs to be connected correctly. First keep a record of where it was by marking it before
disassembling the tubing).
5. Check the valve directly connected to the tubing of the positive-pressure chamber to see 1)
whether the on-off switch is normal; and 2) whether there is any clogging.
6. After troubleshooting, complete the steps shown in the
Remove Error
wizard.
2.2.12.10 Problems in Creating the Negative Pressure
The troubleshooting steps are as follows:
1. Check if the negative-pressure chamber is broken: Disassemble the negative-pressure chamber
if necessary and seal the openings with rubber tubes. Then put the negative-pressure chamber
into the water tank. Use a syringe or other equipment to pressurise the negative-pressure
chamber. Any air bubbles that occur indicate that the negative-pressure chamber needs to be
replaced.
2. Check if there are any kinks or damage along the tubing connected to the negative-pressure
chamber. Any replacements should be made using tubing of the proper length and type.
