Dishwasher Cycle Chart — Condensation Dry System
Which Detergent Ingredients Give Best Dishwasher Performance
Detergent with a separate rinse additive in the dispenser gives better drying performance.
For tough baked on soils an Enzyme detergent is better at hydration of the food soils.
For staining such as tomato, coffee and tea, a detergent with a higher phosphate content
and Chlorine bleach will work on the stains much better than an Enzyme based detergent.
•
Units with a fuse, if it blows there is very low A/C voltage at PCB L1 to N, L1 to Ground will read 120vac.
•
Replace fuse and unit may work properly, usually a "weak fuse“.
•
Neutral is fused, use caution as L1 is hot, you will be “shocked” between L1 and Chassis.
•
Later production the fuse is "hidden" in the wire harness.
•
Newer production (May 2009 Serial *S5*) has no fuse . Dead unit, look for cause,
. if none, replace main PCB (new part #)
