TLDR

On your HOBART LXe SERIES DISHWASHERS unit, the appearance of rust often indicates improper cleaning practices or an issue with your water supply. Common culprits include the use of abrasive steel wool, which damages the stainless steel surface, or high iron content in the incoming water. Addressing these factors promptly will prevent further corrosion and maintain machine longevity.

Technical Details

Repair Steps:

  1. Cease Abrasive Cleaning Methods: Immediately stop using abrasive materials like steel wool, scourers, or harsh chemical cleaners. These can scratch the passivation layer of stainless steel, making it susceptible to rust. Instruct staff on proper cleaning protocols using only soft cloths or sponges and approved commercial dishwasher detergents and descalers.
  2. Inspect Machine Interior for Damage: Carefully examine the interior surfaces of the wash tank, spray arms, and racks for any visible scratches, pitting, or existing rust spots. Pay close attention to areas that may have been aggressively cleaned. Document any damage found.
  3. Test Water Supply for Iron Content: Obtain a water test kit or consult with a local water treatment specialist to test the incoming water supply’s iron content. High levels of ferrous (iron) ions in the water can lead to rust staining and corrosion, especially when combined with heat and detergents.
  4. Consider Water Treatment Solutions: If high iron content is confirmed, explore water treatment options such as a dedicated iron filter, water softener, or reverse osmosis system. Implementing appropriate water filtration can significantly reduce mineral deposits and the potential for rust.
  5. Clean Existing Rust Spots: For existing rust spots, use a non-abrasive, food-safe stainless steel rust remover or a paste made from baking soda and water applied with a soft cloth. Gently rub the affected area, rinse thoroughly, and dry completely. Avoid leaving any cleaning agents to sit for prolonged periods.
  6. Implement Regular Descaling and Maintenance: Establish a routine descaling schedule using an approved commercial descaling agent to prevent mineral buildup, which can exacerbate rust issues. Ensure regular preventative maintenance checks by a qualified technician to monitor machine health and water quality.

Common Questions:

Q: Why is rust appearing in my HOBART LXe dishwasher?

A: Rust in your LXe Series dishwasher is typically caused by using abrasive cleaning tools like steel wool, which damage the stainless steel’s protective layer, or by a high concentration of iron in your water supply.

Q: Can existing rust be removed from the dishwasher?

A: Yes, existing rust spots can often be removed using non-abrasive, food-safe stainless steel rust removers or mild acidic solutions like a baking soda paste, followed by thorough rinsing and drying.

Q: How can I prevent rust from returning in my HOBART LXe dishwasher?

A: To prevent rust, ensure you only use non-abrasive cleaning methods, test your water for high iron content and install appropriate filtration if needed, and maintain a regular descaling schedule.
