Why
Ember explicitly states that their mugs are hand-wash only. The electronic base must never be submerged, and the ceramic coating can be damaged by dishwasher detergents and high heat.
How do you wash Ember mug?
Hand wash the mug with a soft sponge and mild detergent. Do not submerge the base; wipe it with a damp cloth.
What happens if you put Ember mug in the dishwasher?
If you put the Ember mug in the dishwasher, the first wash may not show immediate damage, but the ceramic coating will begin to dull and develop fine hairline cracks (crazing) due to thermal shock and alkaline detergent. After repeated washes, the coating will peel, exposing the stainless steel, which can then rust in the dishwasher's humid environment. The electronic base is the most critical: water can seep past the seal, causing the battery to fail, the charging coil to corrode, and the temperature sensor to malfunction. The mug may stop heating, fail to hold a charge, or even short-circuit. The lid's silicone gasket will harden and lose its seal, leading to leaks. Cosmetic damage (coating peeling, etching) is permanent; functional damage (electronics failure) renders the mug unusable. Ember's warranty explicitly excludes damage from dishwasher use.
Frequently asked questions
- Can I microwave the Ember mug?
- No, the Ember mug contains metal (stainless steel) and electronics, so it is not microwave safe. Microwaving can damage the electronics and cause arcing.
- What is the maximum temperature the Ember mug can withstand?
- The Ember mug is designed to heat beverages up to 145°F (63°C) and can be used with liquids up to about 165°F (74°C). Exposing it to higher temperatures (e.g., boiling water) may damage the ceramic coating or electronics.
- How often should I replace the Ember mug lid?
- The lid should be replaced if the silicone gasket becomes loose, cracked, or fails to seal properly. Under normal hand washing, the lid may last 1-2 years. Ember sells replacement lids separately.
- Can I put the Ember mug in the freezer?
- No, freezing can damage the battery and electronics. The mug is designed for hot beverages only; extreme cold may cause condensation inside the base, leading to corrosion.
