The Toshiba Electric Rice Cooker, model TRSH01, is a household appliance designed for cooking various types of rice and grains, as well as steaming. It incorporates Fuzzy Logic technology to sense moisture levels and accurately adjust heat and timing for optimal cooking results.
Function Description:
The rice cooker offers multiple cooking programs, including:
- LOW CARB: For cooking rice with reduced carbohydrate content. It requires the use of a metal steamer for washing rice and specific water level lines on the steamer. Recommended volume: 1-2 cups.
- QUICK RICE: For faster rice cooking. Recommended volume: 1-5.5 cups. Water levels are based on the "WHITE RICE" line on the inner pan.
- WHITE RICE: Standard program for white rice. Recommended volume: 1-5.5 cups. Water levels are based on the "WHITE RICE" line on the inner pan.
- BROWN RICE: Program for brown rice. Recommended volume: 1-3 cups. Water levels are based on the "BROWN RICE" line on the inner pan.
- MIXED GRAIN: For cooking mixed grains. Recommended volume: 1-3 cups. Water levels are based on the "WHITE RICE" line on the inner pan. Mixed grains require soaking in water above 176°F (80°C) for 2 hours before cooking.
- QUINOA: Program for quinoa. Recommended volume: 1-5.5 cups. Water levels are based on the "WHITE RICE" line on the inner pan.
- STEAM: For steaming food. Default cooking time is 30 minutes, adjustable up to 1 hour or by minute increments using the HR./MIN. buttons. Water levels are based on the "STEAM" line on the inner pan.
- OATMEAL: Program for oatmeal. Recommended volume: 1-2 cups. Water levels are based on the recommended amount for oatmeal.
The appliance features a "Keep Warm" mode that automatically activates after cooking, maintaining food warmth for up to 24 hours. A "Preset" function (Delay Timer) allows users to set two different cooking completion times (Timer1 and Timer2) up to 24 hours in advance, though it's recommended not to exceed 12 hours to prevent food deterioration. The "Preset" function is not available for Quinoa and Oatmeal programs.

Troubleshooting Tips:
The manual provides solutions for common issues such as:
- Rice cooker not operating: Check power cord, power failure, or tripped circuit breaker.
- Mushy, sticky, or clumping rice: Adjust water amount, fluff rice after cooking, or ensure proper rinsing.
- Hard or dry rice: Adjust water amount, or soak rice for a short time.
- Scorched rice: Clean temperature sensor, avoid adding ingredients before water, or reduce soaking time.
- Rice does not taste good: Allow cooker to cool between batches, clean sensors/vents, ensure inner lid/steam vent are attached, use correct ingredient-to-water ratio.
- Unpleasant odor: Normal for first uses (plastic odor). Avoid prolonged "Keep Warm" mode, remove cooked rice promptly, rinse rice thoroughly, clean dirty parts, remove accessories from pot before cooking.
- Dry/discolored rice: Reheat only once, sprinkle with water during reheating, ensure steam vent is attached.
- Steam escaping: Check inner lid/gasket, ensure inner lid/cooking pot are not deformed, clean foreign substances from rim.
- Boiling over/spattering: Ensure inner lid/steam vent are attached, clean steam vent/temperature sensor, select correct program.
- Difficult to close lid: Ensure inner lid is attached properly, remove debris from lid latch well.
- Film on interior of cooking pot: Use a non-abrasive plastic scouring pad to remove starch film.
