Display shows E3 during preheat or pressure build and cooking stops.

Safety first: Unplug the unit and allow it to cool before touching internal surfaces.

• Check inner pot placement: Ensure the original Hamilton Beach inner pot is installed, clean on the outside, and seated flat on the heating plate. Do not use third-party or warped pots.
• Verify liquid level: For pressure cooking, ensure you have at least the minimum liquid specified in the manual (often 1–2 cups). Avoid very thick sauces without enough water.
• Clean the heating plate and pot bottom: Remove any burnt food or residue from the heating plate and the underside of the inner pot. Use a non-abrasive pad and dry thoroughly.
• Reset thermal protection: Some models use a self-resetting thermal cutoff on the heating plate. Let the unit cool for 30–60 minutes, then try again with adequate liquid.
• Inspect thermal fuse (advanced): If the unit repeatedly shows E3 and never heats properly, the thermal fuse or overheat thermostat on the heating plate assembly may be weak or failing and should be tested and replaced if open.
