Next Gen Washing Machine & Dryer
Designing the Human Machine Interface (HMI) for a new-to-market, dual-basket premium washer and dryer system
Role: Principal UX Designer
Year: 2025
Product Type: Embedded / HMI / Physical HMI
Context & Problem Framing
Whirlpool operates in a highly competitive appliance market where meaningful differentiation is increasingly difficult. To differentiate and regain leadership in the premium segment of appliances, the team developed a completely new-to-market dual-basket washer, which enables delicates and regular clothes to be washed at the same time, leading to a reduction in time, energy use, and cognitive effort.
Product Goals:
Reduce total wash time
Lower water and energy usage
Decreased mental overhead for users managing multiple loads
The Question
How do you make a fundamentally new physical capability feel intuitive, trustworthy, and immediately usable, without disrupting deeply ingrained mental models around home laundry?
UX Requirements
Existing technology/engineering panel
Add new function into existing HMI
Don’t disrupt users existing and deep mental model of clothes washing
The Approach
The Human-Machine Interface (HMI) became the primary lever for bridging this gap, not only responsible for control, but for education, motivation, and confidence-building during first-time and repeat user.

Constraints & Realities
Legacy engineering architecture: The HMI was built on an existing control platform, limiting flexibility in input types, system states, and responsiveness.
Regulatory and safety requirements: Specific interaction rules, e.g. button hold durations, lovk behaviors, were mandated to prevent unsafe use (child safety and accidental activation)
Multi-brand considerations: The solution needed to scale across Whirlpool and Maytag, requiring subtle brand differentiation without fragementing the core interaction model
Technical debt and late-stage validation: Early Industrial Design assumptions had not been fully stress-tested, requiring UX to reconcile usability issues later in the process without expanding scope or timelines.
Stakeholder misalignement: Marketing priorities around feature visibility occasionally conflicted with UX goals of clarity and cognitive simplicity
Limiting sensing and feedback technology: The machine could not “know” what users asumed it would, requiring careful expectation-setting through the interface
These constraints made it clear that success would depend less on visual polish, and more on clear system logic and interaction discipline.
Behind each Human Machine Interface that the user sees is hardware and specifically placed technologi

Discovery & Insights
Early assumptions suggested that the dual-basket functionality could be introduced via a single new control on the HMI. However, when we mapped real user scenarios across the laundry lifecycle, from load planning to cycle completion, this approach quickly broke down.
Through journey mapping, user flow exploration, internal and secondary research, and system modeling we uncovered several critical insights.
Critical Insights:
Laundry is a habitual, low-attention activity - users rely heavily on muscle memory and pattern recognition
Introducing choice at the wrong moment increases hesitation and error, more than empowerment
Users need reassurance that the emachine was “doing the thing right” especially when two loads behaved differently within a single cycle.
Transitions between setup, active wash, and completion were the moment of highest confusion and opportunity.
The insight was not that users needed more control, but that they needed better timing, clearer feedback, and reduced deciision making burden.

Design Strategy
Initial assumptions suggested the feature could be introduced with a single HMI control. However, scenario mapping revealed the interaction was more complex, requiring a deeper dive into the flow to ensure we were could support real-world use.
Our strategy focused on three priorities:
• Making the new capability intuitive through contextual guidance and progressive disclosure
• Reducing cognitive load by automating or clearly signaling key transitions
• Designing scalable interaction patterns to support future products
Execution
During the design execution phase phase, I focused on translating the strategy into a robust, testable interaction system
Early concepts explored multiple mental models for dual-basket washers, included system-led automation, parallel clows, master-secondary relationship
Iterative Refinement narrowed the solution to a model that balanced established system hardware with user agency
Detailed flows and specs defined edge cases, validation rules, and feedback states
Component definitions ensured consistency across waher and dryer interfaces while allowing brand-level differentiation
Rather than optimizing individual screens, the work prioritized flow integrity across time - from first interaction to cycle completion.
