3. Check if Liquid Pump P1 is working; if not, replace the pump.
4. Check if the negative 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
negative pressure is normal in status interface. If it is normal after the replacement, this means
that the negative-pressure sensor and the corresponding electrical circuit have caused a
problem with building negative 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 tubing of the negative-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.

Troubleshooting steps are as follows:
1. Check if the two tubes are connected correctly in pinch valve LV12. First confirm that they are
correctly positioned; then determine whether both soft tubes are tucked into the bottom of the
tank (as shown in Figure 2-36). (Note that the position of tubes marked in red in the following
figure shall not be installed reversely.)
