Critical tacho signal - no tacho signal for 5

From Service Manual 856860, p.32:

1.Check connection and wire harness to wash motor

2.Measure the heating element resistance across the terminals with the leads removed. Expected: 11 to 13 ohms.

3.Verify the thermal fuse and high-limit thermostat show continuity. An open safety in series with the element produces a no-heat fault even when the element tests good.
