Kunezimpawu eziningana ezibonisa ukuthi umshini wakho wokuhlanza amanzi udinga isihlungi esisha. Nazi ezinye zezimpawu ezivame kakhulu:

1. Iphunga noma ukunambitheka okubi: Uma amanzi akho enephunga noma ukunambitheka okungajwayelekile, kungaba uphawu lokuthi isihlungi sakho asisasebenzi kahle

2. Isivinini sokuhlunga esihamba kancane: Uma umshini wakho wokukhipha amanzi uthatha isikhathi eside kunokujwayelekile ukuhlunga amanzi, kungaba uphawu lokuthi isihlungi sakho sivalekile futhi sidinga ukushintshwa.

3. Umfutho wamanzi ophansi: Uma ubona ukwehla komfutho wamanzi, kungaba uphawu lokuthi isihlungi sakho sivalekile futhi sidinga ukushintshwa.

4. Inani eliphezulu lamagaloni asetshenzisiwe: Izihlungi eziningi zihlala isikhathi eside ngamagaloni athile amanzi. Uma ususebenzise inani eliphezulu lamagaloni, sekuyisikhathi sokushintsha isihlungi.

5. Isibani sesikhombisi sesihlungi: Ezinye izihlinzeki zokuhlanza amanzi ziza nesibani sesikhombisi sesihlungi esizokhanya uma sekuyisikhathi sokushintsha isihlungi.
