Power surges are one of the biggest causes of washing machine failures in Harare. When power returns after load shedding, the supply can spike or fluctuate for a few seconds, which is enough to damage sensitive electronics. Summer storms add lightning to the risk.
The good news is that a few simple habits and some affordable equipment prevent most of this damage.
Simple habits that make a big difference
- Switch the machine off at the wall when the power goes off.
- Wait a few minutes after power returns before switching on.
- Unplug the machine during thunderstorms.
- Avoid starting a wash just before scheduled load shedding.
Surge protectors and voltage protectors
A surge protector absorbs short spikes, while a voltage protector (sometimes called a power guard) disconnects the appliance if voltage goes too high or too low and reconnects after a delay. For washing machines in Harare, a good voltage protector with a time delay offers the best everyday protection.
Choose a unit rated for the machine’s power draw, especially if you use hot washes.
Running a washing machine on solar or an inverter
Many Harare homes now run on solar and inverters. Washing machines can run on inverter power if the inverter is large enough and provides a pure sine wave output. Heating draws the most power, so cold or eco programmes are best when running on batteries.
If your machine trips the inverter or behaves strangely on inverter power, the inverter may be undersized or the machine may have a fault. We can test both.
Generators
Small generators can produce unstable voltage and frequency, which is hard on electronics. Use a voltage protector between the generator and the machine, and avoid heating cycles on small generators.
