The spring torsion of the pressure disk holder can short with
the terminal of the battery on the Control PCB, causing the
battery to discharge and therefore it is not backing up the
RAM resulting in Error 5.
For pumps manufactured prior to July 1999 with serial
numbers 7001-13344 and below it is necessary to remove
4mm of the Spring torsion with cutters where shown in
Figure 3.
