Amana
E8
LockoutHigh-stage PS stuck closed
High-stage pressure switch is made with the inducer not on high.
Walk E8 in Diagnose
5 plates — walk the one on the cabinet
First check
1 Unplug the switch with the inducer off
On Amana AMVC96 this code is the switch made when the inducer is not running. Unplug that switch only. This is the second switch — do not confuse with E1.
Expect: Code changes when the harness is open.
If fail: Wrong switch, or the IFC input is shorted.
If pass: Switch/hose path. Go to step 2.
The rest of the walkthrough is Diagnose.
On the plates
- This is the second switch — do not confuse with E1.
- Welded HPS or water-filled hose.
- IFC calling high when it should be low — W2 shorted to W1.
- IFC calling high when it should be low — W2 shorted to W1 on 24V fallback.
- This is Category I metal vent. There is no 96% collector or PVC trap to prime.
- Cap, liner, common-vent tables, inducer wheel, hose on the inducer housing.

Same number, other makers
E8 on Amana is not the same code on these plates.
