Thanks. Let me clear.
1. When WH is at full CCW, it trip at ~4 bars. That said Turn the SC trimmer on the gauge until 6 of the 8 bars are lit up.. Should be 4 of 8 bars, not 6 of the 8 bars.
2. Use the BAR link during the SYS test and see where the "B" setting is. You should unplug the red and blue harness to stop any water getting into the engine. The result B is 4 bars.
