how to descale keurig b70 manual

The Keurig B70 is a single-serve coffee brewing system that requires regular descaling to maintain optimal performance and extend its lifespan. Descaling removes mineral buildup from the internal components caused by hard water. Below are comprehensive instructions for the descaling process, including preparation, step-by-step procedure, safety precautions, and troubleshooting tips.

Descaling Overview

Descaling is essential for removing calcium and lime deposits that accumulate in the internal water system. The Keurig B70 features an automated descaling mode to simplify this maintenance process.

Preparation

Gather necessary supplies and prepare the brewer for descaling.

1. Empty water reservoir and remove any water filter.
2. Prepare descaling solution: Use Keurig descaling solution or white vinegar alternative.
3. Ensure brewer is cool and powered on.
4. Remove any K-Cup pod from the brew chamber.
5. Place a large mug (at least 12 oz) on the drip tray.

WARNING! Never use harsh chemicals or abrasive cleaners. Use only approved descaling solutions.

Step-by-Step Descaling Process

Follow these exact steps to properly descale your Keurig B70.

1. Power off brewer and unplug from electrical outlet for 30 seconds.
2. Plug brewer back in and power on.
3. Press and hold 8 oz and 10 oz brew buttons simultaneously for 3 seconds to enter descaling mode.
4. Add descaling solution to water reservoir, then fill remainder with water.
5. Press POWER button to begin descaling cycle.
6. Brewer will automatically dispense solution in intervals - empty mug as needed.
7. When reservoir is empty, refill with fresh water only.
8. Continue brewing cycles until "Add Water" light illuminates.
9. Allow brewer to complete final rinse cycle.

CAUTION! Do not interrupt the descaling cycle once started. The process takes approximately 30 minutes.

Descaling Solution Options

• Keurig Official Descaling Solution: Recommended for optimal results and warranty compliance.
• White Vinegar Alternative: Mix 1 part white vinegar with 3 parts water (use as last resort).
• Citric Acid Solution: 1 tablespoon food-grade citric acid per quart of water.
• Lemon Juice: Not recommended as it may leave residue.

Note: Commercial descaling solutions are formulated specifically for coffee makers and provide best results.

Safety Precautions

Always follow safety guidelines during the descaling process.

Electrical Safety: Unplug brewer before any maintenance. Keep water away from electrical components.

Chemical Safety: Wear gloves when handling descaling solutions. Avoid contact with eyes and skin.

Brewer Safety: Ensure brewer is cool before starting. Never force components during process.

Post-Descaling: Always run multiple rinse cycles to remove all solution residue.

Post-Descaling Brewing

After descaling, perform these steps before normal use.

1. Run 2-3 additional brew cycles with fresh water only.
2. Check that "Descale" indicator light is no longer illuminated.
3. Brew a test cup of hot water to ensure no descaling solution remains.
4. Reinstall water filter if previously removed.
5. Resume normal brewing operations.

Tip: If any vinegar taste remains, run additional rinse cycles until water tastes clean.
